Gunmen from an al-Qaida inspired militia have taken over radio and television stations in the central Libyan city of Sirte, a security official said. He said the seizure of the buildings happened on Thursday after militants from Ansar al-Sharia had warned the station to stop broadcasting music. The group, considered a terrorist organization by the United States, is accused of being involved in a deadly 2012 attack on a US mission and annex in Benghazi. Its branch in the city of Derna has pledged allegiance to the Islamic State group. On Saturday, a bomb hit a pipeline leading to the country’s largest oil field, al-Sarir, disrupting the flow of oil to ships at a coastal terminal, oil officials said.
