Kabul:  At least 11 Taliban insurgents were killed and 12 others captured in joint operations by Afghan and coalition forces in various parts of the country, where a soldier of the US-led International Security Assistance Force (ISAF) lost his life due to a "non-battle related injury".

During 15 joint Afghan and coalition forces operations since on Saturday, 11 insurgents were killed, one was injured and 12 others were captured across the country, the Afghan Interior Ministry said in a statement on Sunday.

"51 kilogram of opium, different kinds of light and heavy weapons, with some amount of explosives were confiscated during the operations," the statement said.

In a separate incident, an ISAF service member died on Saturday in eastern Afghanistan "as a result of a non-battle related injury," a statement from ISAF said.

A total of 40 ISAF service members had been killed last month in different parts of the country in separate incidents. Among those killed were 14 US, 12 Turkish and nine British soldiers.

The coalition forces had announced yesterday that two top commanders of the dreaded Haqqani network of Taliban, responsible for attacks on allied troops, had been arrested in joint military operations by the Afghan and US-led soldiers in eastern Afghanistan.
