Explosion in Pakistan kills four

At least four people were killed and 30 injured in an explosion near a mosque in the Pakistani port city of Karachi Friday.

The blast took place in the Delhi Colony area of the city and shattered the window panes of many nearby buildings, damaged motorcycles and completely destroyed a vehicle bearing a government number plate, Dawn online reported.

Sindh Information Minister Sharjeel Memon has confirmed that three government vehicles also were damaged in the attack and that these vehicles were the apparent target of the blast.

Khaliq Sheikh, deputy inspector general of police, said the blast was carried out through a bomb planted in a motorcycle.

Eyewitnesses reported that the explosion occurred when people were leaving the mosque after Friday prayers.

The injured were shifted to Jinnah Postgraduate Medical Centre in Karachi.

The police have taken two suspects into custody who were shifted to an undisclosed location for questioning.

Earlier Thursday, four people, including a senior police official, were killed in a suicide blast near Karachi's old wholesale vegetable market.
