Ghundi, 19 August (AKI) — At least 50 people were killed and over 100 others were wounded in a huge blast at a mosque Friday in Pakistan’s northwest Khyber tribal area, Pakistan’s Aaj TV reported, citing officials.

Pakistan’s DawnNews quoted local administrator Fazal Khan as saying there was some evidence the bombing of the Jamrud mosque in Ghundi village was a suicide attack.

No group immediately claimed responsibility for the bombing, but Pakistan’s tribal belt is a hotbed of militant activity, as well as sectarian rivalry.

Hundreds of people were at the mosque for Friday prayers when the bomb exploded, according to media reports. Some reports said up to 500 people were inside the mosque at the time of the blast.

The entire mosque collapsed following the blast, according to the media reports and many people were said to have been buried under the debris of the collapsed mosque.
