Attackers hurled hand grenades into a mosque on Friday in north-western Pakistan, killing at least three worshippers and injuring more than 18, government officials said, DPA reports.
The attack came hours after a suicide bombing killed 45 people in a suicide attack at another mosque in the same region.
The second strike took place in Badabir, a suburb of Peshawar, the capital of the north-western province of Khyber-Pakhtunkhwa.
"The attackers hurled three hand grenades when people were offering Isha prayer (evening prayer). Around 60 to 70 people were inside the mosque," said Ijaz Khan, a senior police official.
The Taliban claimed responsibility for the first mosque attack.
