Pro-Libyan government forces fighting to dislodge Islamic State from its key bastion of Sirte have found bodies of militants, handcuffed and shot in the head, inside army barracks in the city.
Libyan media official Ahmed Hadiya said at least six bodies were found in the al-Saadi barracks after the facility was overrun by forces allied to the UN-brokered government.
He said he believes the bodies are of IS "militants who wanted to flee".
He added that the offensive to capture the Mediterranean city is nearing its "final stage" and IS fighters have hunkered down inside a sprawling convention centre for the final showdown.
IS has exploited Libya's turmoil to gain a foothold in the North African country.
