Attackers Torch NATO Supply Convoy in Pakistan VOA News 09 June 2010 Pakistani drivers examine burnt trucks torched by suspect militants in an attack in Sangjani, near Islamabad, Pakistan, 09 Jun 2010 Photo: AP Pakistani drivers examine burnt trucks torched by suspect militants in an attack in Sangjani, near Islamabad, Pakistan, 09 Jun 2010 Gunmen have attacked a truck stop just outside of the Pakistani capital, torching a convoy of tankers and trucks bound for NATO forces in Afghanistan. Pakistani officials said 10 to 15 gunmen began shooting at the depot, just 10 kilometers from Islamabad, Tuesday before setting at least 30 trucks on fire. They said the attackers then fled in cars and on motorcycles. Officials said at least seven people were killed, including some truck drivers. One driver said he was sitting inside his truck when the attack began and heard the gunmen saying "Kill the drivers" and not to let anyone escape. This is not the first time militants have attacked trucks carrying supplies for U.S. and NATO forces in Afghanistan, but it is rare for such attacks to take place so close to Islamabad. Earlier Tuesday, fierce clashes on the Orakzai tribal agency killed six soldiers and 40 militants. Local officials said the fighting broke out after militants stormed a checkpoint in the northwest, prompting a retaliatory strike by the army. At least 10 militants and 15 security personnel were reported wounded in the violence. The casualties can not be confirmed because the remote area is off-limits to journalists and other independent observers. News of the fighting comes just a week after the Pakistani military declared it had successfully completed military operations in Orakzai tribal agency. In North Waziristan Tuesday, the Pakistani Taliban staged a public execution of a man accused of killing two brothers. Hundreds of people gathered in the town of Miran Shah to watch as a relative of the slain brothers shot the man. Â The execution highlights the influence the Taliban still wields in the North Waziristan tribal region, which borders Afghanistan.
