Bahrain ferry disaster: Death toll revised up to 57

A Bahrain Interior Ministry official has increased the death toll from last night's ferry disaster to 57.

The ferry carrying up to 150 people capsized and sank last night overturned less than a mile off the coast of Bahrain.

Interior Ministry spokesman Colonel Tarik al-Hassan told Al-Jazeera television that 67 people were rescued.

Al-Hassan said not all the identities of the 57 dead were known as many of them did not carry identification papers.

He said the exact number of passengers was not known because some left the boat before it sailed.
