A spokesperson for the Lady Reading Hospital said that it had received 7 dead and 70 injured, many of them suffering from burns due to the blast, according to Reuters.
While the official in the Pakistani police and Qara`azim confirmed to Agence France-Presse, "The explosion occurred during a Qur’an lesson, when one of them brought a (booby trapped) bag into the teaching class. Several students were killed and others were injured.
The bombing took place after months of relative calm in Pakistan, especially in Peshawar, in the north of the country, which witnessed daily attacks in the past before the security situation bettered there.
The Taliban had previously carried out an attack on a school in Peshawar in December 2014, killing more than 250 people, most of them children, which prompted the Pakistani army to intensify its operations against the armed groups.
Peshawar is the regional capital of the Pakistani province of Khyber Pakhtunkhwa, which borders Afghanistan.
The province was the scene of such attacks in recent years, and sectarian violence has also resulted in the killing or injury of worshipers inside mosques or students at religious institutes across Pakistan.
Two days ago, 3 people were killed in an explosion in the southwestern city of Quetta.
