US-led Coalition forces in Afghanistan have killed five Taliban subcommanders in recent weeks, including a bomb-maker and two behind the August 18 attack that left 10 French soldiers dead, they said.

"Coalition forces have positively identified five Taliban subcommanders killed during operations over the past month in Kapisa province," the Coalition said in a statement from Bagram Air Field in Afghanistan, and released in Washington.

Among the five were Ahmad Shah and Mullah Rohoullah, killed with six others by airstrikes in Nijrab district on August 30 after coalition forces ran into armed resistance while searching a compound.

Both were heavily involved in helping move weapons and foreign fighters into Afghanistan, the statement said, as well as facilitating Taliban operations, including the August 18 ambush on the French patrol.

Ten French soldiers were killed and another 21 injured in the attack by about 100 Taliban in Sarobi, 50 kilometres (30 miles) east of Kabul.

It was the deadliest ground battle for international soldiers in the country since they toppled the Taliban regime in 2001.

Coalition forces said that on August 23 they killed subcommanders Khairullah Nezami and Qari Ezmarai in Tag Ab district.

Nezami, they said, helped to arrange the making and planting of bombs and coordinated the movement of suicide bombers in the Taliban network.

A fifth subcommander, Qari Nejat, was killed together with four additional insurgents in an operation in Nijrab district on August 5.

The Coalition linked Nejat with the July 21 suicide bombing in the Tag Ab bazaar that injured six Afghans, the July 16 kidnapping of three Afghan policemen in Jalokhel, and the torture and beheading of an Afghan on June 30.
