MISRATA: At least four people were killed on Wednesday in a Daesh suicide bomb attack at the main court building in Libya’s third-largest city Misrata, security officials said.

The officials said a suicide bomber was able to detonate an explosive vest inside the building in the centre of Misrata, a coastal city about 200km east of Tripoli.

“Three men belonging to the Daesh militant organisation carried out a suicide attack against the court complex in Misrata killing four people and wounding 15 others,” General Mohammed Ghassri, a spokesman for armed forces in Misrata that are loyal to the country’s internationally backed government, said.

He said the three men got out of a vehicle and one was able to push his way into the building and set off explosives. Of the other two, one was shot dead and the other arrested, Ghassri said.

There was no immediate claim of responsibility from Daesh for Wednesday’s attack.

Separately, production at Libya’s giant Sharara oilfield resumed on Wednesday after an armed brigade forced a two-day shutdown, the National Oil Corporation (NOC) said.

Operations at Sharara, which is crucial to a partial revival of Libya’s oil output, have been repeatedly disrupted this year due to blockades by armed groups, protests and security problems.

As production resumed, the NOC lifted force majeure on loadings of Sharara crude from Zawiya port, where the tanker Seaways Hatteras was due to load a 130,000 tonne cargo, according to shipping fixtures and a Libyan oil source.
