A passenger bus overturned late Tuesday on a road in South Africa's Eastern Cape province, killing least 11 people.

Officials say the accident happened after a tire blew out on the bus, causing the driver to lose control.

Local media reports say dozens were injured in the accident, some severely.

The crash comes after last week's accident in the Western Cape province, when 14 children and a driver died after their school bus plunged into a lake in the southern city of Knysna.
