Four dead in Bangladesh riot over offensive Facebook post

(CNN)Four people were killed Sunday when Bangladesh police fired on a crowd after clashes erupted over a Facebook post that angered Muslims.

Thousands of people took to the streets in the town of Borhanuddin, in Bangladesh's southern Bhola district, to protest the post that allegedly criticized the Prophet Muhammad.

"We had to fire, we had no options," said AKM Ehsanullah, a senior police official in the Barisal Range, Bangladesh.
