Libya's internationally-recognized Prime Minister Abdullah al-Thinni said his government's air force was responsible for strikes on the airport of the capital Tripoli, controlled by a rival administration, a statement said on Tuesday. "The air strikes on Mitiga airport were conducted by the national air force to target the group Libya Dawn," Thinni's government website quoted him as saying. He was referring to an armed group backing the rival government controlling Tripoli. Thinni was speaking after UN special envoy Bernadino Leon had asked him to end the air strikes, according to the statement. Tripoli's Mitiga airport has been hit twice since Monday. http://english.ahram.org.eg/News/116431.aspx
