Several airstrikes and explosions shook the Libyan capital overnight, residents said, in an escalation of a two-week offensive by eastern forces on Tripoli, which is held by the internationally recognized government.

A Reuters reporter and several residents said they saw an aircraft circling for more than 10 minutes over the capital late on Saturday, and that it made a humming sound before opening fire on several areas.

An aircraft was heard again after midnight, circling for more than 10 minutes before a heavy explosion shook the ground.
