Officials say a rocket attack on a U.S. base has killed three Afghans.

NATO spokesman Michael Cole told VOA that several rockets hit Bagram Airfield in Parwan province late Monday, destroying one helicopter and damaging several others.

Afghan officials said Tuesday three Afghan intelligence agents inside the helicopter were killed. Afghan and international service members were also said to be wounded in the attack.

The Taliban claimed responsibility for the assault that came hours after the U.S. forces transferred control of the prison at Bagram to Afghan authorities.

Also Tuesday, NATO said a coalition airstrike killed two senior Taliban leaders in eastern Afghanistan.

The coalition said one of the men, Mullah Hazrat, was the suspected mastermind of the August 2008 ambush on NATO troops that killed 10 French soldiers and wounded 21 others in Uzbin Valley, south of Kabul.

French, American and Afghan soldiers later launched a major offensive in the region to give control of the Taliban stronghold back to local security forces.

NATO says Hazrat and one of his associates, Shakir, were killed Sunday in the Alisheng district of Laghman province. The coalition says Hazrat is believed to have ordered several attacks against Afghan and coalition forces in recent months, including the use of suicide bombers in Kabul.

NATO says the senior Taliban leader also coordinated the movement of foreign insurgents from Pakistan into Afghanistan.

The coalition says no civilians were harmed during Sunday's airstrike.

All international combat forces are to withdraw from Afghanistan by the end of 2014 after transferring security responsibility to their Afghan counterparts.

In May, French President Francois Hollande said he plans to pull all of France's 2,000 combat troops out of Afghanistan by the end of the year, an earlier timeline than put forth by his predecessor, Nicolas Sarkozy. France has the fifth largest foreign contingent in Afghanistan.
