Suspected militants armed with guns and rockets on Monday blew up a tanker carrying fuel through Pakistan for NATO troops based in neighboring Afghanistan, police said.

According to a private TV channel, several armed men lobbed a rocket and then opened fire on the supply convoy on the outskirts of Pakistan's northwestern city of Peshawar, senior police officer Imtiaz Ahmed said.

"The attack triggered a huge fire and destroyed one tanker. Its driver escaped unhurt but his helper was wounded," he said.

In a subsequent exchange of fire lasting up to an hour, Pakistani security forces killed a militant, said police officer Karim Khan.
