Q: London (CNN) -- Four current and former employees of Britain's Sun newspaper were arrested by authorities investigating claims of inappropriate payments to police, News Corp. and police said Saturday. Police searched the men's homes as well as the East London offices of News International, the News Corp. subsidiary that publishes the Sun and other U.K. newspapers, London's Metropolitan Police Service said. A 29-year-old police officer was also arrested Saturday at the central London police station where he works, police said, on suspicion of corruption, misconduct in a public office and conspiracy in relation to both offenses. He works for the force's Territorial Policing command. Three of the men were arrested at their homes -- two of them, aged 49 and 57, in the county of Essex, and one aged 48 in London. A fourth, aged 42, was arrested at an east London police station. By late Saturday, police said that all five men were subsequently released after posting bail. The current and past newspaper employees were all set to "return pending further inquiries" in April or May, according to the Scotland Yard statement. Earlier, they'd been questioned on suspicion of corruption, aiding and abetting misconduct in a public office, and conspiracy in relation to those offenses. The operation "relates to suspected payments to police officers and is not about seeking journalists to reveal confidential sources in relation to information that has been obtained legitimately," an earlier police statement said. News Corp. said it is cooperating with the search of its News International offices. Police said the operation was the result of information provided to police by News Corporation's Management and Standards Committee (MSC), which was set up to look into conduct at News International, a subsidiary of News Corp. The News Corp. statement said the company had "made a commitment last summer that unacceptable news gathering practices by individuals in the past would not be repeated." The committee was asked "to proactively co-operate with law enforcement and other authorities if potentially relevant information arose at those titles. As a result of that review, which is ongoing, the MSC provided information to the Elveden investigation which led to today's arrests." The Sun, which is Britain's best-selling tabloid newspaper, was the sister paper of News International's now-defunct Sunday title, the News of the World. A spokeswoman for News International earlier declined to comment on the search of its offices. The investigation into alleged corruption, known as Operation Elveden, is being run in conjunction with an inquiry into phone hacking prompted by allegations of wrongdoing at News of the World. The best-selling News of the World tabloid was shuttered in July amid outrage over claims that its staff hacked the voicemail of a missing 13-year-old girl who turned out to have been murdered. James Murdoch, chief executive of News International and the son of media mogul Rupert Murdoch, has insisted that the practice of phone hacking was not widespread. News Group Newspapers, a subsidiary of News International that was the publisher of News of the World, agreed to payouts in the High Court totaling hundreds of thousands of dollars earlier this month over phone hacking claims. Among those who read statements in court were Labour Party lawmaker Chris Bryant, former Deputy Prime Minister John Prescott, actor Jude Law, the actor's ex-wife Sadie Frost, and high-profile rugby player Gavin Henson. News International said the company "made no admission as part of these settlements that directors or senior employees knew about the wrongdoing by NGN or sought to conceal it. However, for the purpose of reaching these settlements only, NGN agreed that the damages to be paid to claimants should be assessed as if this was the case." Both James and Rupert Murdoch, as well as senior executives at News International, have testified before British lawmakers examining allegations of wrongdoing. A public inquiry has also been set up to look at claims of widespread misconduct by the British media. Representatives of a range of news outlets have appeared before it. There have been 13 arrests in connection with Operation Elveden and 17 in relation to Operation Weeting, the phone hacking inquiry, the Metropolitan Police confirmed. Three people have been arrested in connection with both investigations. Operation Elveden is overseen by the British police watchdog, the Independent Police Complaints Commission.

Q: Seoul, South Korea (CNN) -- South Korea will conduct naval fire drills near a flashpoint with the North that resulted in the deaths of four people, military officials said Thursday. The South Korean Joint Chiefs of Staff announced the exercises will take place in the seas southwest of Yeonpyeong Island on a day to be announced between December 18 and 21. The South previously announced military exercises for this week, but Thursday's announcement adds to them. Tensions mounted between the Koreas on November 23, when North Korea shelled the island, which lies in South Korean territory. The attacked killed two marines and two civilians and injured 18 people. Last month's attack was the first direct artillery assault on South Korea since 1953, when an armistice ended fighting. The North has accused the South of provoking the attack because shells from a South Korean military drill landed in the North's waters. North Korea Thursday accused the South's new defense minister, Kim Kwan-jin, of "going reckless like a puppy knowing no fear of a tiger," state-run KCNA reported. During his confirmation hearing this month, Kim said South Korea would respond with airstrikes if the North attacks it again. The South Korean joint chiefs said the drills will be carried out in the presence of officials from the Military Armistice Committee and representatives from U.N. party members to ensure that the exercise is lawful and follows rules of the armistice.

Q: (CNN) -- We celebrate Veterans Day this week, but we have been riding a crest of war remembrance for months now. World War I's centenary alone has brought forth new books -- histories of that war, based on historical documentation and letters unearthed in family and state archives. We look anew at the inscriptions on tombs of known and unknown soldiers and posters from the past whose propagandistic messages shout at us across the divide of time. Opinion: How a century-old war affects you . But in the midst of this flood of words, an equally significant, and telling, aspect of the Great War has been largely overlooked: the place of silence in and around the conflict. World War I may call to mind the written word -- the harrowing verses of Wilfred Owen or the prose of Erich Maria Remarque, whose "All Quiet on the Western Front" rendered war's raw brutality. But the experiences of the years 1914-1918 in fact enshrined the notions that language cannot adequately express the experience of combat, that the veteran will often remain silent about war, even to his or her own family, that the speech of soldiers -- the euphemisms and slang used on the battlefield, the coded communications used after, among veterans -- leaves out as much as it reveals. Opinion: When the flu wiped out millions . This notion of war as an inaccessible space may seem almost antiquated today, when civilian smartphones and video cameras produce a continual feed of chaotic combat situations. But much of what goes on in military operations remains unknown to those who were not there. The connections between silence and war still hold among soldiers-- for reasons of security, censorship, military culture and enduring mechanisms of human psychology. Opinion: The mighty women of World War I . In 2014, as in 1914, many veterans keep quiet about what are their most life-changing experiences. There is, for one thing, the trauma; there is also the desire to protect one's family. There is guilt over killing -- and guilt over surviving. And there is the sheer difficulty of how to explain it: how to put an exceptional state into everyday language. Opinion: How World War I gave us 'cooties' World War I was a watershed in this regard, modeling, during the course of the conflict, what could and could not be said about war by combatants. Some silences were strategic: Soldiers knew their communications home would be censored, and it was unwise to appear defeatist or unpatriotic by conveying the horrors of the battlefield. Opinion: The promise World War I couldn't keep . Others refused speech as a way of respecting the war experience of fallen comrades. War poetry is vocal on the need for restraint to counter the rhetoric of heroism produced by those far from the front. In his 1915 poem "When You See Millions of the Mouthless Dead," Charles Hamilton Sorley scorned the use of "soft words" about those who could not speak back: "Say only this, 'They are dead.' /Then add thereto, /'Yet many a better one has died before.'..." Opinion: The 'bionic men' of World War I . Most combatants could not come up with the words, soft or hard, to communicate to those back home what lay around them: carnage on an unprecedented scale. With many new weapons, and others used on a mass scale for the first time in history, World War I inaugurated a new human experience of battle and devastating new injuries. Even the educated felt that language failed them to convey the sights and smells of bodies rent by machine gun fire, devastated by bombs from the air, blistered from gas or paralyzed by shell shock. "I cannot find words to translate my impressions. Hell cannot be so terrible," wrote the French lieutenant Alfred Joubaire in his diary, unable to draw comparisons with any known reality. Opinion: War: What is it good for? Art! The writings, drawings and other artifacts that flowed from the front grappled not only with the question of how to rise to these expressive challenges, but whether it is even possible to communicate this new reality to the noncombatant. Opinion: Should nations pay the price for their leaders' misdeeds? Henri Barbusse reflected on this futility in his 1916 novel "Under Fire," which originated from notes taken during his time at the front. "It'll be no good telling about it, eh? They wouldn't believe you ... no one can know it. Only us," remarks one soldier. "No, not even us, not even us!," another responds. "We've seen too much to remember ... We're not made to hold it all." Traumatic repression, the veterans' despair at being understood, the affirmation of a special bond of knowledge and experience among comrades -- all familiar struggles from our modern wars. They are all here, in 1916 -- violence of a scope that exceeded comprehension. Indeed, Barbusse's scene ends with the rueful reflection that this war was something "you can't give a name to." Opinion: The promise World War I couldn't keep . Both the modern figure of the literary witness and the modern figure of the mute veteran emerged from this early 20th-century conflagration -- as with Barbusse, they were often one and the same - and with them the notion of war as something too overwhelming to tell. Opinion: How World War I gave us drones . Of course, this situation was not unique to the Great War. A study released in August by the United States Department of Veterans Affairs, which reveals the prolonged post-traumatic stress among Vietnam veterans -- home from war for 40 years now -- reminds us of that. Opinion: How World War I gave us drones . And so it's fitting that from 1919 onward, World War I's November 11th Armistice has been marked in many countries through two minutes of silence and has been expanded to include the veterans of all wars. The words of World War I can enlighten us about the conflict 100 years later. But the spaces of silence around the din of all wars can tell us much about war's toll on those who wage it -- in 2014 as in 1914. Photo blog: WWI: The Golden Age of postcards .
