A teenage suicide bomber on Sunday struck a religious gathering of the Shia community killing at least 30 people and injuring nearly 200 others in the town of Chakwal in Punjab province, hours after security forces were targetted near UN office in the heart of the federal capital.
The suicide attacker detonated his explosives near the gate of an Imambargah or prayer hall in Chakwal, some 90 kilometers south of Islamabad, when he was barred from entering the complex by persons guarding the entrance.
About 2,000 worshippers had gathered for 'majlis' - a religious ceremony - at the Imambargah when the attack occurred a little after 12.30 pm local time. Thirty people were killed by the blast, state-run APP news agency reported.
There was no official word on the incident though witnesses and reporters said nearly 200 people were injured in the blast. Witnesses said the suicide bomber was aged about 16 or 17 years and was dressed in black.
TV channels beamed footage of blood and body parts spattered on the wall near the gate of the Imambargah. No group claimed responsibility for the attack.
Earlier reports had said the bomber had managed to enter the Imambargah. Witnesses said the death toll would have been much higher if the attacker had not been stopped at the gate.
