Palestinian media sources said Thursday that unknown gunmen blew up late last night a hair salon in the city of Beit Hanoun, in the northern Gaza Strip. Witnesses said that unknown gunmen placed an explosive device at the shop’s front door and detonated it from a distance. The explosion at the shop caused damage to nearby stores, but no injuries were reported. The Gaza Strip has recently seen a series of explosions of shops and cafes, at a time when the Palestinian interior minister has launched a security plan in order to contain internal unrest throughout the coastal region.
