Fateh Jang - A suicide bomb attack on an army vehicle killed five people including two senior army officers near Pakistan's capital Islamabad Wednesday, officials said.
The attack happened on a main road just outside the town of Fateh Jang 40km west of Islamabad, local police official Ghulam Majeed told AFP.
Details of how the bomber reached the vehicle are not yet clear.
"Two officers, namely Lieutenant Colonels Zahir Shah and Arshad, and three civilians embraced shahadat [martyrdom] when a security forces vehicle was targeted by a suicide bomber," a security official told AFP.
The bomber was also killed.
An AFP reporter at the scene said the area had been cordoned off and traffic had come to a standstill.
More than 4 000 Pakistani police, paramilitaries or troops have lost their lives to an Islamist insurgency since 2002, but the death of high-ranking officers is rare.
Pakistan opened talks with the Tehreek-e-Taliban Pakistan, the largest militant group, earlier this year but the dialogue has stalled.
The air force carried out attacks in the North Waziristan tribal district late last month that killed at least 75 people, as speculation mounted of an impending military ground operation in the area.
