REYKJAVIK, Iceland - Iceland closed its main international airport and canceled domestic flights Sunday due to a powerful volcanic eruption.

Airport and air traffic control operator ISAVIA said Keflavik airport, the country's main hub, was closed at 0830GMT (4:30 a.m. EDT), and would stay shut for the rest of the day.

In April 2010, officials closed the continent's air space for five days,fearing the ash could harm jet engines.Some 10 million travelers were stranded.

The Grimsvotn volcano, which lies under the uninhabited Vatnajokull glacierabout 120 miles (200 kilometers) east of the capital, Reykjavik, began erupting Saturday for the first time since 2004. Grimsvotn also erupted in 1998, 1996 and 1993. The eruptions have lasted between a day and several weeks.

University of Iceland geophysicist Magnus Tumi Gudmundsson said this eruption, which began Saturday, was Grimsvotn's largest eruption for 100 years.

John.F.Kennedy  (May 29, 1917 – November 22, 1963), often referred to by his initials JFK, was the 35th President of the United States, serving from 1961 until his assassination in 1963.

After military service as commander of the Motor Torpedo Boats during World War II in the South Pacific, Kennedy represented Massachusetts's 11th congressional district in the U.S. House of Representatives from 1947 to 1953 as a Democrat. Thereafter, he served in the U.S. Senate from 1953 until 1960. Kennedy defeated then Vice President and Republican candidate Richard Nixon in the 1960 U.S. presidential election. He was the youngest elected to the office, at the age of 43,the second-youngest President (after Theodore Roosevelt), and the first president to have been born in the 20th century.Kennedy is the only Catholic president, and is the only president to have won a Pulitzer Prize.Events during his presidency included the Bay of Pigs Invasion, the Cuban Missile Crisis, the building of the Berlin Wall, the Space Race, the African American Civil Rights Movement and early stages of the Vietnam War.

Kennedy was assassinated on November 22, 1963, in Dallas, Texas. Lee Harvey Oswald was charged with the crime, but was shot and killed two days later by Jack Ruby before a trial could take place. The FBI, the Warren Commission, and the House Select Committee on Assassinations (HSCA) concluded that Oswald was the lone assassin, with the HSCA allowing for the possibility of conspiracy based on disputed acoustic evidence. Today, Kennedy continues to rank highly in public opinion ratings of former U.S. presidents.
