Boko Haram leader Abubakar Shekau vowed to disrupt Nigeria's general election in a new video released on Tuesday, after two suicide attacks in the northeast blamed on the Islamists killed 38 people.
"This election will not be held even if we are dead. Even if we are not alive Allah will never allow you to do it,"
Shekau said in the Hausa language, presumably referring to the polls scheduled for 28 March.
The video appeared to be the first message released by the group on Twitter, a sign of its changing media tactics after previous messages were distributed to journalists on DVD.
