Unknown assailants tossed a hand grenade into the office of a pro-Assad Palestinian faction in the refugee camp of Ain al-Hilweh, near the southern city of Sidon early Thursday.
There were no casualties in the dawn attack on the Al-Saiqa office, Palestinian security sources told The Daily Star.
Al-Saiqa is a Palestinian faction created by Syrian Baathists in the 1960s.
