A bomb explosion outside a Muslim Shiite mosque in north Pakistan Tuesday killed at least three people and wounded 14 others in the latest attack to hit the nation, officials said.

The blast took place in the Gracy Lines neighborhood of the garrison city of  Rawalpindi, which neighbors the capital Islamabad, as worshippers prayed inside the mosque, senior police official Akhtar Laleka said.

Hospital officials said at least three people were killed and 14 others were wounded.

"We have three bodies and 14 wounded people at our hospital," Asif Qadir Mir, chief of the local government hospital, told AFP.

Allama Nasir Abbas killed late Sunday in Lahore, the capital of Punjab province, after addressing a religious gathering.

On November 19, gunmen killed a senior Muslim Shiite university director along with his driver in Lahore, while another Shiite leader and his guard were killed in Karachi in early December.
