The US dollar has risen against the euro and the yen on reports that Osama bin Laden has been killed.
The US dollar rose against the euro and the yen after reports on Monday that Al Qaeda leader Osama bin Laden had been killed nearly 10 years after the September 11 attacks.
The dollar rose against the euro, which fetched 1.4764 dollars from 1.4864 in earlier trade. The dollar was at 81.66 yen from 81.19 earlier.
Investors unwound short dollar positions on falls in crude oil prices on the news that bin Laden is dead, Tomohiro Nishida, senior dealer at Chuo Mitsui Trust and Banking, told Dow Jones Newswires.
US President Barack Obama said in a dramatic televised address that bin Laden had been killed in an operation in Pakistan.
US armed forces have been hunting bin Laden for years, an effort that was redoubled following the attacks on the World Trade Centre in New York and the Pentagon, which killed 3,000 people in 2001.
