PROBLEM: NAIROBI, Kenya (CNN) -- Three British guards jumped overboard and were rescued from the water after battling in vain to prevent pirates hijacking a chemical tanker off the coast of Somalia. Three British security guards board a helicopter to be transferred to a Royal Navy vessel. The Liberian-flagged Biscaglia came under "sustained and heavy attack" early Friday morning, Nick Davis, Director of Anti-Piracy Maritime Security Solutions (APMSS), said in a statement. The three APMSS-employed security guards -- all former British servicemen -- mounted "sustained non-lethal resistance" but were unable to stop the attackers seizing control of the ship, Davis said. The trio were airlifted to safety by a German naval helicopter and flown to a French frigate after the vessel summoned assistance from coalition warships. They were later transferred to a British Royal Navy ship. All three were unhurt, Davis said. "I have spoken with my team leader on the phone and he informs me that the level of violence was significant and forced them reluctantly to leave the vessel after every effort was made to ensure the safety of the ships crew," Davis said. Pirates continued to shoot at the three in the water, Davis said. "The hijacked vessel with pirates in control then attempted to run them down." The Biscaglia is managed by Singapore-based Ishima and owned by Winged Foot Shipping in the Marshall Islands and was crewed by 25 Indians and two Bangladeshis who are believed to be still onboard. The vessel is believed to be on its way to an anchorage in Puntland, northeastern Somalia, Davis said. iReport.com: Share your view from 'Inside Africa' Also Friday, pirates released the Greek ship MV Centauri, which was hijacked in September off the coast of Somalia, according to Andrew Mwangura, the head of the Kenya Seafarers Association. There was no immediate information about the 25 crew members on board the ship when it was taken. A multinational naval force including vessels from the U.S., NATO member states, Russia and India has been patrolling the Indian Ocean waters seas near the Gulf of Aden, which connects the Red Sea and the Arabian Sea, following a sharp increase in pirate attacks in the region. Around 20,000 oil tankers, freighters and merchant vessels pass along the crucial shipping route each year. So far this year, pirates have attacked almost 100 vessels off the coast of Somalia coast and successfully hijacked nearly 40, according to the International Maritime Bureau's Piracy Reporting Center. The most high-profile hijacking so far came earlier this month, when pirates seized a Saudi oil tanker carrying $100 million worth of oil and a crew of 25, although that attack occurred outside the pirates' normal operational range, 450 nautical miles southeast of Mombasa, Kenya. Pirates are still holding the ship. Another vessel held since September is the Ukrainian MV Farina, which was carrying a cargo of weapons and tanks and a crew of 22. In an interview provided to CNN this week, a pirate leader claimed attacks on shipping would continue as long as life in Somalia remained desperate. "The pirates are living between life and death," said the pirate leader, identified by only one name, Boyah. "Who can stop them? Americans and British all put together cannot do anything." The interview was conducted in August by journalists working for the Somali news organization, Garowe.

PROBLEM: (CNN) -- An American woman died aboard a cruise ship that docked at Rio de Janeiro on Tuesday, the same ship on which 86 passengers previously fell ill, according to the state-run Brazilian news agency, Agencia Brasil. The American tourist died aboard the MS Veendam, owned by cruise operator Holland America. Federal Police told Agencia Brasil that forensic doctors were investigating her death. The ship's doctors told police that the woman was elderly and suffered from diabetes and hypertension, according the agency. The other passengers came down with diarrhea prior to her death during an earlier part of the trip, the ship's doctors said. The Veendam left New York 36 days ago for a South America tour.

PROBLEM: (CNN) -- In brief remarks to the media just after returning to her hometown of Seattle, an emotional Amanda Knox thanked those who believed in her and supported her fight to overturn her murder conviction in Italy. "I'm really overwhelmed right now," said a tearful Knox, who arrived to cheering supporters at Seattle-Tacoma International Airport. "I was looking down from the airplane, and it seemed like everything wasn't real." "What's important for me to say is just thank you, to everyone who has believed in me, who has defended me, who has supported my family," she said, her voice shaking. Being with her family, she said, is "the most important thing to me right now." "Thank you for being there for me," she said. Knox and her family were on a British Airways flight that landed in Seattle about 8:12 p.m. ET. Before beginning her remarks, Knox smiled and said, "They're reminding me to speak in English, because I'm having problems with that." An Italian appeals court on Monday overturned Knox's murder conviction in the 2007 death of her roommate, British student Meredith Kercher. Knox initially was sentenced to 26 years in prison. Knox's mother and stepfather, Edda and Curt Mellas, also thanked those who have supported their family, as well as the Italian attorneys who fought on her behalf. "Meredith was Amanda's friend," said Philadelphia attorney Theodore Simon, who spoke at the news conference. Knox wants the Kercher family to be remembered, Simon said as Knox nodded and appeared to fight tears. Knox supporters in Seattle said they planned a rousing welcome. "To Amanda herself, we say, 'Way to go, kid,' " Tom Wright, founder of the group Friends of Amanda Knox, said Monday night. "We look forward to welcoming you home with open arms and open hearts," Wright said, reading a statement. "You have well deserved, and will well deserve, all the joy and warmth and fun of your normal life returned to you." The statement also said that it was "primarily a sad occasion," and that the group's "deepest sympathies" were with Kercher's family. CNN affiliate KOMO-TV reported that Wright was among a group of more than a dozen supporters who gathered at a hotel suite to watch the jury return its decision about Knox more than 5,000 miles away. Afterward, Margaret Ralph was among those crying tears of joy. Asked what she'll say when she sees Knox, Ralph told KOMO, "I won't say anything. I'll just give her a big hug and kiss." "It was incredible," fellow supporter Kellanne Henry told KOMO, adding that it took a minute to absorb the news. "They finally got it right," she said. Many Seattle residents took to social media to post messages. "I am so happy this nightmare is over for you," Seattle resident Jenn Whitney wrote in a posting on one of several Facebook pages devoted to Knox. Whitney said she "cried with joy" when Knox's conviction was overturned. "I pray that God brings you home safely," she added. "If I had the chance to greet her when she lands back here in Seattle, the only thing I would do is hand her a rose, give her a hug and say 'welcome home!' " Jeff Bamby posted. On another Facebook page, Tamara Slater wrote, "Amanda you have been in the prayers of so many people, it must be heart warming to know you were never forgotten. Welcome home!" CNN affiliate KIRO-TV reported that when staff went out to gauge reactions to the news out of Italy on Monday, "We met just a few people in West Seattle who disagreed with Monday's ruling and thought that Knox was guilty." Jordan Adams said he thought Knox was guilty, but he was willing to accept the decision to overturn the conviction. "I did think she was guilty, but I guess, good luck to her since she's been freed and cleared," he told KIRO. Early Tuesday morning, a jogger who spotted a CNN crew in Seattle's Queen Anne Hill neighborhood stopped and yelled, "Yay Amanda! Welcome home!" But later, another resident walked up to a CNN crew to say that she could not "care less about Knox returning home" and that she believed Knox committed the crime. CNN's Josh Levs and Sandra Endo contributed to this report.
