At least 28 people were killed and dozens injured in an air strike on a military school in Libya’s capital Tripoli.

Spokesman for the health ministry of the Government of National Accord has confirmed the air strike. At the time of the strike the cadets were gathered on a parade ground before going to their dormitories.

The southern part of Tripoli has seen fierce fighting since last April, when military strongman Khalifa Haftar began an offensive against the GNA.

Libya was plunged into chaos with the toppling and killing of longtime dictator Muammar Gaddafi in a 2011 NATO-backed uprising. It has since become divided between the GNA and rival authorities based in the country’s east.
