Sources: Yemen authorities sure tanker blast was deliberate attack

Yemen is sure that the blast which ripped through a French tanker off its coast last Sunday was a deliberate attack but the identity of the perpetrators is still unknown, Yemeni sources said on Sunday. 

"Yemen is now convinced that it was a pre-meditated act but the question remains of who did it," one of the sources close to the government-led investigation told Reuters. 

Yemen initially said the blast was an accident, but it has since raised the possibility of an attack. (Albawaba.com)
