Security officials in Afghanistan say a strong explosion near Kabul shook the capital early today (Saturday), but caused no known injuries or damage.
Officials with the International Security Assistance Force in Kabul say the blast came from the direction of the airport outside the city. The cause of the explosion is unknown.
The Afghan Islamic Press reports that three explosions have been heard in the area.
Meanwhile, Afghan officials now say at least 25 people were killed in a series of powerful explosions at a munitions depot late Thursday and early Friday near the southern border town of Spin Boldak. Dozens of other people were injured.
The cause of the blasts is under investigation.
Rescue teams are still searching through the rubble. The French news agency reports that occasional explosions are still going off, hampering rescue and clean-up efforts. Several buildings in the area were destroyed.
