A relative of prime-minister designate Faiez Serraj was murdered in Tripoli this morning in what appears to have been a car-jacking.Details are limited of the killing of a man who some sources are describing as a cousin of Serraj. Dr Nasser Serraj, an obstetrician and gynaecologist practicing in the capital, had apparently just climbed into his car after leaving dawn prayers at an unidentified mosque. Gunmen ran up and ordered him out of his vehicle. When he refused he was shot dead. The attackers reportedly then pulled his body from the car and drove off in it.
