MIRANSHAH, Pakistan: At least two militants were killed and two others were injured when a bomb exploded Tuesday in a restive Pakistani tribal region near the Afghan border, officials said.
The morning attack came as a group of militants were visiting the bazaar in Miranshah, the main town in North Waziristan, known as a stronghold of Taliban and Al-Qaeda linked militants.
"It was a remote control bomb which targeted Tehreek-e-Taliban Pakistan (TTP) militants. Two of them have been killed and two others are injured," intelligence sources told AFP.
A militant source confirmed the attack, and said that those killed were members of the main faction of the TTP, headed by warlord Mullah Fazlullah.
No group immediately claimed responsibility for the attack, but infighting between different Taliban factions have killed dozens of people in the area recently.
Washington calls the region the most dangerous place in the world.
The latest attack comes two weeks after the Pakistani Taliban formally ended a ceasefire called to promote talks with the government aimed at ending the militants' bloody seven-year insurgency.
Prime Minister Nawaz Sharif's government began negotiations with the TTP through intermediaries in February, with the ceasefire beginning March 1.
Since the TTP rose up against the Pakistani state in 2007, more than 6,800 people have been killed in bomb and gun attacks around Pakistan, according to an AFP tally.
