Reuters reports:
Nine coalition troops were killed on Tuesday when a helicopter crashed in Afghanistan's south, the NATO-led force said, making 2010 the deadliest year of the nine-year war.
Two NATO service members, an Afghan soldier and a U.S. civilian were wounded in the crash. They were taken to hospital for treatment, the International Security Assistance Force (ISAF) said in a statement.
There was no indication of the nationality of the dead troops, ISAF said in a statement. An ISAF spokesman said more information would be released later.
There was no enemy fire in the area when the aircraft crashed and the cause is under investigation, ISAF said.
The deaths take the toll so far in 2010 to at least 529, according to monitoring website iCasualties.org. Last year, the previous deadliest, 521 foreign troops were killed.
