A series of explosions across Afghanistan on Thursday killed at least 10 people and wounded scores more, according to police and hospital officials.

No one immediately took responsibility for the deadly explosions.

The worst of the three attacks occurred in northern Mazar-e-Sharif where at least 10 worshippers were killed as they knelt in prayer, said Dr. Ghawsuddin Anwari, head of the main hospital in northern Mazar-e-Sharif. Another 40 were injured. They were brought in ambulances and private cars.
