A deadly explosion occurred at a mosque in Peshawar, northern Pakistan, on Monday afternoon as a large crowd gathered for prayer.

Local authorities said 28 people have been confirmed dead and about 120 wounded.

A police officer said some people are still trapped under debris.

Nobody has claimed responsibility for the blast, but police suspect it was a terrorist attack.

The Pakistani Taliban unilaterally declared an end to the ceasefire agreement with the government last year and resumed terror attacks across the country.
