Officials in Pakistan say at least 59 people have been killed in attacks at mosques in the northwest of the country. In the second attack, a grenade was thrown into a mosque on the outskirts of Peshawar, killing at least four people. In the earlier incident, a suicide bomber blew himself up as people were leaving a mosque after Friday prayers in a suburb of Darra Adam Khel, killing 54 people, including the son of this eyewitness, Fazal Ur Rehman.

"The prayers finished and the Mullah stood to offer a khutbah, the speech for the Jummah prayer. He, the suicide bomber started running on the steps. He was wearing a red shirt and he had a long beard. And as he reached the door, suddenly the blast occurred, and it became dark everywhere. In this incident, my child died."
