Thirty people, including two children, were killed and nearly 50 others injured when a suspected suicide bomber struck a religious gathering in Dera Ghazi Khan town in Pakistan's Punjab province on Thursday.
The blast occurred shortly before 7 pm when about 100 people had joined a religious procession outside an imambargah or Shia prayer hall. Officials said about a dozen people were killed on the spot while others died in hospital.
Local health official Natiq Hayat said 30 people had died and 48 others were injured in the blast. He said information about the casualties was still being compiled. Three or four of the injured were in a critical condition, he added.
Other officials said two children were among the dead. Hayat said some of the bodies were unidentifiable.
No group claimed responsibility for the attack.
Witnesses said they saw bodies and many injured persons lying on the road after the blast. Police officials said initial investigations suggested the blast was caused by a suicide bomber as there was no crater at the site of the attack.
