At least four people were killed after a loud explosion rocked a madrassah located in Pakistan's Kuchlak area on the outskirts of Quetta, police said.

Iran Press/Asia: Twenty-two others were also wounded in the blast that took place after Friday prayers in Pakistan's Kuchlak, and the wounded people were transferred to Civil Hospital Quetta. 

The imam of the mosque inside the seminary, located 25km from the city of Quetta, was killed in the explosion, reported DawnNewsTV. 

“The blast was carried out through a timed device that was planted under the wooden chair of the prayer leader,” said Quetta police chief Abdul Razzaq Cheema.

This is the fourth explosion that has taken place in Quetta over the past four weeks. On July 23, a blast had occurred in the Eastern Bypass area which left four people dead and 32 injured.

The Balochistan cabinet had last month vowed to bring terrorists and their facilitators to justice and said that such attacks could not weaken the determination of the government against terrorists and their masters.
