In Pakistan, a bomb explosion in the southern port city of Karachi has killed at least two people and wounded several others.
Police and relief workers in Karachi say the bomb went off early Friday morning at the entrance of a multistory building, killing a security guard and a passerby instantly.
They say casualties were low because the blast occurred before the start of office hours. The building sits on the main road that leads to Karachi's airport.
Authorities say the explosion was caused by a three-kilogram bomb set off by a timing device. No one has taken responsibility for what police are calling an act of terrorism.
Karachi is Pakistan's largest city and commercial center. It has been the scene of political, religious and ethnic violence, killing hundreds of people, in recent years.
Friday's bombing came a week after an attack on a Shiite Muslim mosque in the southwestern city of Quetta killed at least 48 people. Suspected militants from the majority Sunni Muslims were blamed for the attack.
