At least six children have been injured in Libya in a grenade attack on a school in Benghazi, officials say.
Witnesses say the grenade was thrown over a wall into a private school in the Tabilinu area during a break from lessons.
Benghazi has witnessed a series of bomb attacks and assassinations within the past year, but attacks on schools are rare.
It is not yet known who is responsible for the attack.
He then threw it into the school before escaping in a low black car, the eyewitness said.
People were running and screaming after the blast, the resident said.
The blast occurred just before 11:00 local time (09:00 GMT), while the children were outside playing.
A Benghazi security official said the explosion was "weak" and said that police were currently looking for the perpetrators.
Benghazi was the cradle of the 2011 uprising that toppled the 42-year reign of dictator Muammar Gaddafi.
Since then however it has been a hotspot for attacks on public institutions and officials.
