Libya has reopened Tripoli's only functioning airport, according to a posting on the airport authorities' Facebook page on Sunday.
Mitiga airport was closed earlier in the day after residents reported an air strike on the Libyan capital.
A Reuters reporter and several residents said they saw an aircraft circling for more than 10 minutes over the capital with a humming sound before opening fire.
Witnesses had reported drone strikes in the past days but there has been no confirmation.
Explosions heard in the city center this time were louder than in previous days, Reuters reported.
