user: Text: NATO's chief urged Russia on Friday to pull back its troops from its border with Ukraine. Russia should contribute "to a de-escalation of the situation" and engage in a direct dialogue with the Ukrainian government, NATO Secretary General Anders Fogh Rasmussen said during a visit to Sofia, Bulgaria. NATO is "not discussing military actions" but is focused on protecting its allies, and it "will take all steps necessary to make sure that this collective defense is effective," Rasmussen said. Meanwhile, the organization is reinforcing support to its allies, "from the Baltic to the Black Sea," to deal with the instability created by Russia, Rasmussen said via Twitter. NATO released additional satellite images Friday purportedly showing the Russian military buildup and rebutted Russian claims that other satellite photos released a day earlier were outdated. NATO said the photos were recent, gathered between late March and earlier this month. "It is clear that the military buildup of forces occurred in early March 2014," NATO said. Meanwhile, the destroyer USS Donald Cook has entered the Black Sea on a mission to demonstrate the U.S. "commitment to our allies and to enhance security readiness in the region," Navy spokesman Lt. Shawn P. Eklund said Friday. Russia has called the U.S. military move, however, part of a systemic NATO buildup in the Black Sea. An international crisis arose in Ukraine after Russia annexed its Crimean Peninsula in March under a pact signed by Russian President Vladimir Putin with the Prime Minister of Crimea and the mayor of the city of Sevastopol. Earlier, in a Crimean referendum, 96.7% of ballots favored Crimea leaving Ukraine and being annexed by Russia. The United States now estimates there are up to 40,000 Russian troops near the border, based on classified and commercial satellite imagery. Russia has no intention to additionally annex the southeastern regions of Ukraine, Foreign Minister Sergey Lavrov said Friday in a televised interview on Russian state television, the state-run ITAR-Tass news agency reported. "This would run counter to the vital interests of Russia," Lavrov said, while adding that there is no need to deploy peacekeepers in Ukraine nor any need for United Nations Security Council decisions on the matter. Lavrov went on to say that there are no Russian troops or Russian secret services agents in southeastern Ukraine. CNN's Michael Martinez and Pierre Meilhan contributed to this report.

Question: Heavily armed militants staged an attack on a U.N. peacekeepers' base that was sheltering civilians in South Sudan on Thursday, killing at least 48 people and seriously injuring dozens more, a U.N. spokesman in the country said Friday. The attack on the U.N. base in Bor, the capital of Jonglei state, began when militants used rocket-propelled grenades to breach the compound, U.N. spokesman Joseph Contreras said. Contreras said the gunmen then opened fire at the base, where peacekeepers had been hosting and protecting nearly 5,000 civilians. Details about how the attack ended were not immediately available, but the death toll is expected to rise, Contreras said. A search of the site continued Friday, he said. United Nations Secretary-General Ban Ki-moon strongly condemned the violence. Ban called the attack a "serious escalation." Any attack on U.N. peacekeepers is "unacceptable and constitutes a war crime," the Ban said in a statement released on Thursday. He also called on the government to take immediate steps to protect all U.N. bases in the country. South Sudan erupted in violence in mid-December when rebels loyal to ousted Vice President Riek Machar tried to stage a coup to oust President Salva Kiir. Since then, militia loyal to Machar have battled government forces. Violence has quickly spread, with reports of mass killings emerging nationwide. South Sudan seceded from Sudan in 2011 after decades of war. But numerous armed groups have remained active in the oil-rich country.

in: a hip, and often unbearably hot, place to check out up-and-coming bands and DJs. Dimitriou's Jazz Alley (2033 Sixth Avenue) is an excellent jazz venue and there's live music almost every night at the Tractor Tavern (5213 Ballard Avenue). The cowboy boots dangling from the ceiling are a clue to the music policy, which tends towards folk, alt-country and bluegrass. For something completely different, there's Teatro ZinZanni (222 Mercer Street), an OTT spectacular of the weird and wonderful. Tickets start at $104 and grant you access to a surreal combination of circus, cabaret and fine dining. The five-course menu was created by famed Seattle chef Tom Douglas and is accompanied by a three-hour show of vaudeville-inspired wackiness.
