A blast struck a checkpoint in the southern Libyan city of Sebha on Sunday, killing at least two people including a senior police officer, local police, city officials and medics said, Trend reports citing Reuters.
A security source in Sebha said the blast was caused by a suicide bomber who detonated a car bomb.
Sebha is in the deep south of Libya, about 130 kilometres (80 miles) from Taraghin, where Islamic State carried out a bomb attack last year that caused no casualties.
