Security officials say Libyan war planes have bombed militia bases in the eastern city of Benghazi, as part of a campaign by a rogue former general to root out insurgents in the area.
Forces loyal to former general Khalifa Haftar launched two airstrikes on the compound of the February 17 Martyrs Brigade west of the city Wednesday.
No casualties were reported, but witnesses say there was structural damage.
The February 17 brigade is made up of former Islamist ex-rebels and are one of the largest militant groups in Benghazi.
General Haftar and his National Libyan Army have been fighting militants for months in Benghazi, Libya's second largest city. Haftar has said he aims to crush Islamists he accuses of seizing control of the country.
