Dozens killed in blast at Shia mosque in Pakistan’s Peshawar

More than 50 people were injured in the blast, according to Mohammad Asim, spokesman for Peshawar’s Lady Reading Hospital, where the victims were being treated.

Peshawar Police Chief Muhammad Aijaz Khan told CNN that the source of the blast was suspected to be a suicide attack, but the investigation was ongoing.

There has so far been no claim of responsibility for the attack, one of the deadliest in recent years on Pakistan’s Shia minority, which has long been the target of violence by Sunni Muslim Islamist militant groups, including Pakistani TalibanOr Tehreek-e-Taliban Pakistan.

According to Human Rights Watch and other watchdog groups, sectarian violence in Pakistan has killed thousands, many of whom are Shia Muslims.

According to CNN data, it is the deadliest attack in Pakistan since last August.
