A roadside explosion killed 12 civilians and wounded four in southern Yemen on Monday when a bomb targeting a military car hit their vehicle instead, a security source said.

"The bomb was planted on a road in the Qaataba district of Daleh province and hit a civilian vehicle instead," said the source, who requested anonymity as he was not authorised to brief the press.

Daleh, south of Yemen's rebel-held capital Sanaa, is controlled by government forces.
