The wife of Cameroon’s deputy prime minister Amadou Ali, has been abducted by the Nigerian militant group, Boko Haram, according to Cameroonian military.

Members of Boko Haram attacked the northern town of Kolofata and also kidnapped the town’s mayor Seini Boukar Lamine.

"I can confirm that the home of vice-prime minister Amadou Ali in Kolofata came under a savage attack from Boko Haram militants," Issa Tchiroma told Reuters by telephone.

The Israeli government has accepted a request by the UN to extend the truce agreed on Friday by another 24 hours, although Hamas earlier rejected an earlier move by Israel to extend the initial 12-hour ceasefire by four hours.

Hamas demanded a complete withdrawal by Israeli troops from the Gaza strip and continued to fire rockets into Israel, claiming that the country was using the truce to prepare more attacks.

The US became the latest country to close its mission in Tripoli after violent clashes between militias escalated over the past few weeks and moved closer to the embassy.

"Due to the ongoing violence resulting from clashes between Libyan militias in the immediate vicinity of the US embassy in Tripoli, we have temporarily relocated all of our personnel out of Libya," spokesperson, Marie Harf, said.
