Islamabad, Pakistan (CNN) -- The Pakistani Taliban is claiming responsibility for two recent attacks on trucks carrying supplies for NATO, a central spokesman for the militant group told CNN by telephone Monday.
One of the attacks took place Friday against a convoy of NATO supplies near Shikarpur in the southern Sindh province. The other took place Sunday in the capital of Islamabad, killing three local guards.
Azam Tariq, the Pakistani Taliban spokesman, said both the recent attacks on NATO supply efforts were carried out as revenge for drone strikes and NATO's attacks in Pakistan.
"U.S. and NATO forces are killing innocent Pakistanis, which is unacceptable, and we will teach them a lesson by such attacks," Tariq said.
On Monday, Islamabad police said four people were arrested in connection with the Sunday attack, which also left eight drivers injured.
A third convoy was attacked in Baluchistan on Friday, killing a driver and his aide. The Taliban has not claimed responsibility for that attack.
