Blast in Yemeni prison allows 40 prisoners to escape

ADEN, Yemen (Reuters) - A bomb exploded in a prison in the southern Yemeni province of Dalea on Thursday, injuring four inmates and allowing around 40 prisoners to escape, a government official said.

Witnesses and southern media said all those who fled the police jail belonged to Yemen's southern secessionist movement, which opposes the rule of President Ali Abdullah Saleh.
