Some 10 days after disappearing in Yemen, three members of an Al Jazeera Arabic news crew have been released by their kidnappers, the Doha-based media network has said.

Correspondent Hamdi al-Bokari, cameraman Abdulaziz al-Sabri and driver Moneer al-Sabai were taken while filming in the besieged southern Yemeni city of Taiz. Al Jazeera said the identity of their captors was unclear and did not say what prompted the kidnappers to release the men.
