(CNN) -- Afghan and coalition troops killed at least seven insurgents during an operation in eastern Afghanistan, NATO's International Assistance Security Force said Sunday.
The deceased include Sayed Karim, a Taliban sub-commander who led at least 15 insurgent fighters and planned attacks against Afghan civilians as well as Afghan and coalition forces, the force said.
The troops were headed toward a targeted compound in Nangarhar province when insurgents began firing from the primary compound and an adjacent compound Saturday, the security force said.
Three insurgents died after the two sides exchanged fire and coalition forces conducted an air strike, the force said.
Four insurgents were later killed after Afghan and coalition troops cleared the area, the security force said.
No civilian deaths or injuries were reported.
