boosted security on Saturday fearing further attacks a day after a suicide bombing during protests at Islamabad’s pro- Red Mosque killed 14 people.
Authorities were also investigating how the attacker was able to strike at a crowded market in the heart of the capital, the 13th suicide blast to hit the country since a bloody army raid on the mosque on July 10.
The bomber targeted officers who were policing Islamic students who had occupied the controversial Red Mosque to demand that their jailed former cleric should lead prayers after its chaotic reopening on Friday.
“Security has been tightened and a joint investigation team has been assembled,” Interior Ministry spokesman Brigadier Javed Cheema told AFP.
Cheema added that the remains of the suicide bomber had been found and were being DNA tested to establish his identity.
He said the mosque had been closed indefinitely, adding the suicide attack was “in all probability linked to the Red Mosque issue.”
Islamabad police chief Iftikhar Chaudhry said 56 people had been arrested over the mosque disturbance and were being interrogated, but no one had yet claimed responsibility for the attack.
“There are indications that the bomber may have tried to carry out a suicide attack at the Red Mosque but because of the tight security he was prevented,” a senior security official told AFP on condition of anonymity.
The attacker “found an opportunity where a police unit was assembled and blew himself up.”
The official added that there was a likelihood of more suicide attacks to come.
A senior militant source said the attack showed that Islamic rebels had “ready-made suicide bombers who can be launched at short notice.”
The violence has cranked up pressure on President Pervez Musharraf, who is fending off US threats to launch unilateral military strikes in‘s tribal areas bordering Afghanistan.
Musharraf, who launched a crackdown on extremism after 9/11, won plaudits for tackling militants holed up in the mosque, but the loss of more than 100 lives in the operation to clear it sparked the current militant backlash.
Following heavy fighting between government troops and militants at the mosque earlier this month, the badly-damaged building was repaired and the adjoining girls’ religious school was demolished.
Government workers repainted the formerly red building in pale yellow and patched bullet holes and scorch marks from explosions. The mosque was formally reopened for Friday’s traditional prayers.
However, hundreds of radical students chased out a government-picked religious elder who was meant to lead the prayers and demanded the return of the mosque’s chief cleric, Abdul Aziz, who is now in jail on terror charges.
The protesters defiantly daubed red paint over the walls and police in riot gear later fired teargas at rock-throwing demonstrators.
What threatened to become a dangerous standoff ended suddenly with the sound of the huge blast at the Aabpara market just a few hundred metres (yards) away. The government originally cracked down on the mosque after it led a-style vigilante campaign for Sharia law that climaxed with the abduction in of seven citizens from .
Musharraf has also been facing pressure after losing a legal battle with Pakistan’s top judge that could yet undermine his eight-year military rule. He seized power in a coup in 1999.
The government denied reports on Friday that Musharraf had held a secret meeting with exiled premier Benazir Bhutto inin a bid to arrange a power sharing pact to steady his position.
