Islamabad - At least 22 people were killed and dozens more injured as an explosion ripped through a Shiite mosque Sunday in Pakistan's eastern province of Punjab, government officials said.
A suicide bomber blew himself up at the main entrance of the mosque in Chakwal district, some 90 kilometres south-west of capital Islamabad, when the security guards challenged him.
"At least 22 people are killed and more than 50 are injured, many of them critically," said provincial law minister Rana Sanaullah.
