QUETTA, Pakistan (AP) — Pakistani police say assailants have fired rockets at tankers carrying fuel for U.S-led troops in Afghanistan, setting at least 10 vehicles on fire.

The attack Thursday was the first since Pakistan closed the border for trucks carrying Afghan war supplies to protest a Nov. 26 NATO airstrike that killed 24 Pakistani troops on the Pakistan-Afghanistan border.

Police officer Hamid Shakil says the tanker attack took place at a roadside terminal close to the southwestern city of Quetta.

There were no immediate reports of casualties.

ISLAMABAD (AP) — Secretary of State Hillary Rodham Clinton says the U.S. expects Pakistani President Asif Ali Zardari will return to his duties after receiving treatment related to a heart condition in a Dubai hospital.

Zardari was undergoing tests this week for the condition, triggering rumors that he may be stepping down citing ill health.

The Pakistani president has been under pressure since the nation's ambassador to the U.S. was forced to resign amid allegations he sent a memo to Washington asking for its help in reining in Pakistan's powerful military.

Clinton told reporters in Brussels Thursday the U.S. expects Zardari will receive the necessary treatment "and will be able to return in full health in his duties."

A Pakistani presidency statement says Zardari's health is improving.
