In Pakistan on Monday, a suicide bomber targeted a mosque during midday prayers, leaving at least 25 people dead and 120 injured.

Around 150 worshipers, including some police officers from nearby police stations, were inside the mosque in Peshawar, northwest Pakistan, when the attacker detonated his suicide vest.

According to Zafar Khan, a local police officer, the impact of the explosion caused the mosque’s roof to collapse, which caused several injuries.

According to Daily Mail, Saddique Khan, a top police official in Peshawar who provided the most recent casualty totals, no one immediately claimed responsibility for the bombing.

However, similar suicide attacks have already been linked to Pakistani Taliban.

A 38-years-old Police officer, Meena Gul, who is said to be a survivor said he was present when the bomb went off, claimed to have been inside the mosque but was unable to describe how he managed to escape unharmed.

Gul claimed that following the explosion, he heard cries and screams.

Rescue operations to clear the mosque’s grounds of piles of debris and reach worshipers still buried beneath it are still in progress, according to the police.

Many of the injured people are reportedly being treated at a hospital in critical condition. There is concern that the death toll may increase.

In a statement, Prime Minister Shahbaz Sharif condemned the bombing and instructed officials to ensure that the victims received the best medical care possible.

In addition, he promised to take “severe action” against the perpetrators of the crime.

In a tweet online, Imran Khan, a former prime minister, also condemned the blast and referred to it as a “terrorist suicide attack”
