KARACHI, Pakistan - At least 25 people have been injured in a string of explosions in the southern Pakistani city of Karachi.
Police say five blasts occurred within an hour of each other and took place in both residential and commercial areas.
The Karachi bombings come a day after a deadly suicide bombing in the capital, Islamabad, on Sunday.
Eighteen people died in that blast, most of them police officers.
It was unclear if any security personnel were among the wounded in Monday's blast. Television footage showed ambulances rushing people through crowded streets to hospitals, and wounded lying in hospital beds with bloody bandages.
Karachi, Pakistan's commercial hub, is a teeming port city where militant and political violence commonly breaks out.
In October, former prime minister Benazir Bhutto narrowly escaped a suicide attack that struck a rally of thousands of supporters welcoming her home from exile. More than 140 people died in that attack.
Bhutto was slain later in an attack in Rawalpindi in December.
