More than 1000 inmates have escaped from a prison near the eastern Libyan city of Benghazi.
Gunmen outside the al-Kwafiya jail reportedly fired into the air as inmates started fires.
The jailbreak followed the assassination of a prominent political activist, which sparked protests in the area.
The funeral of Abdul Salam Al-Musmari, a well known critic of the influential Muslim Brotherhood, was held on Saturday. He was killed in a drive-by shooting.
Demonstrations over Al-Musmari’s death spread to the capital Tripoli. Some protesters stormed a Muslim Brotherhood office, as they demanded that Islamist parties be dissolved.
Al-Musmari headed a group credited with launching the 2011 protests against Libya’s longtime dictator Moammar Gadhafi.
