Islamabad, Pakistan (CNN) -- Another oil tanker carrying fuel for NATO troops in Afghanistan was attacked Tuesday near the Pakistan-Afghanistan border, a Khyber Agency official told CNN.
The tanker had been parked at Torkham, said Adil Waseem, senior administration official of Khyber Agency. A bomb planted on the tanker exploded, partially damaging the vehicle. The tanker did not catch fire, and no casualties were reported.
At least four other attacks have been carried out on convoys for NATO since Friday, resulting in the deaths of at least six people.
The Pakistani Taliban has claimed responsibility for two of those attacks, a central spokesman for the militant group told CNN by telephone Monday.
Azam Tariq, the Pakistani Taliban spokesman, said both the 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.
Islamabad police said four people have been arrested in connection with the Sunday attack, which also left eight drivers injured.
