Three men riding on a motorbike at Sufaid Sang road of Peshawar when a grenade carrying by them exploded leaving all of them dead, police said.
“They were suicide bombers and worn suicide jackets,” police officials said.
They were probably going to perform an act of terrorism when a grenade with them accidentally exploded, police sources said.
Recently, in two remote-controlled roadside bomb attacks in Peshawar a policeman was killed and 17 others were injured.
Pakistan, which has suffered from years of jihadist militant violence, has killed and arrested hundreds of suspected militants under a major crackdown launched afterwards.
The Peshawar school attack was seen as having hardened Pakistan’s resolve to fight militants along its lawless border with Afghanistan.
According to AFP: A suicide bomber in northwest Pakistan on Friday accidentally detonated his vest while riding a motorcycle on an empty road, killing himself and two other militants also on bike, police said.
The incident took place in the Sufaid Sang suburb just northwest of Peshawar, the region’s major city, where the trio were likely planning an attack, a senior local police official told AFP.
“Their plan was foiled when the suicide vest of one suicide bomber detonated prematurely,” Kashif Zulfiqar said.
“Their target was not known but they were moving towards a crowded area where there are several police and military check posts,” he added.
Police defused a jacket fitted on the dead body of a second would-be bomber and recovered a Kalashnikov rifle, eight hand grenades and hundreds of live bullets.
Mubarak Zeb, Peshawar police chief confirmed the incident to AFP.
The Pakistani Taliban and other Islamist groups regularly target military and civilian installations as part of an insurgency, which has claimed tens of thousands of lives since it began in 2004.
