SUKKUR, July 25: The body of another suicide bomber was found on Thursday in the parking area of the ISI office which had been attacked on Wednesday.

According to official sources, three ISI officials and a brother of the gardener of the Commissioner House were killed in the attack. Reports on Wednesday said that four attackers had been killed.

The bodies of suicide bombers were taken to the civil hospital in Sukkur amid tight security.

The sources said that a team of ISI officials had arrived here from Karachi and inspected the blast site.

A police team headed by SP CID Karachi Raja Umer Khattab is also investigating the incident.

Intelligence agencies have sealed the ‘red zone’ area of Barrage Colony and Rangers personnel deployed there are not allowing movement of public.

Two suicide jackets found in the debris have been defused by the bomb disposal squad.

The suicide bombers had attacked the ISI office with automatic weapons and hand-grenades. The ISI personnel returned fire and killed three of the attackers.

The sources said the attackers had hurled more than 40 grenades on the ISI building and 34 of them went off one by one and the remaining six were found by the bomb disposal squad.

Law-enforcement agencies and police have so far arrested five to seven suspects and looking for others in different areas.

DIG Sukkur Range Jawed Alam Odho and Commissioner Sukkur Dr Niaz Ali Abbasi told newsmen that 40kg of explosives had been used in the attack.

The ISI building was destroyed and major portions of the DIG House and Commissioner House were damaged by the explosion. Walls of a hotel collapsed and cracks appeared in other nearby buildings.

SSP Sukkur Irfan Baloch told Dawn that Shahzore truck had been used in the attack, like in the earlier strike on the Rangers Headquarters in Karachi.

He said that the terrorist whose body had been found was carrying dry fruit and dates in his pockets, indicating that the attackers planned a hold-up and taking hostages.

He said the affected area had been cleared and police were patrolling and strictly checking people at entry and exit points of the city.

Meanwhile, funeral prayers for Major Zeeshan, Hawaldar Azizullah and Asif Ali were offered at Pano Aqil Cantonment on Thursday. The body of Major Zeeshan was sent to his native town Sialkot and of Azizullah and Asif Ali to Hyderabad.

The brother of the gardener of the Commissioner House was laid to rest in a local graveyard.

AFP adds: According to a spokesman for the Rangers, the dead include five attackers, and four police and intelligence officials.

Officials had previously put the death toll at seven, saying on Wednesday that the five attackers, one intelligence agent and another government official had been killed.

State TV said at least 38 people were wounded.

“We rounded up several people on Wednesday night after the attack and are interrogating them,” the Rangers official said.
