The Islamic State group claimed responsibility for a Tuesday night explosion at the French Cultural Center in Gaza City, according to an unverified proclamation published Wednesday morning in the Strip.

The announcement said this was “the debut operation for the Islamic State group in the Gaza Strip.”

Around midnight local time, several explosions rocked the French Cultural Center, causing damage but no casualties. The center resides in an upscale new building built two years ago.

The declaration released Wednesday morning was topped with the recognizable Islamic State group’s logo. “Our fighters successfully bombed the center for immorality and heresy known as the French Cultural Center after weeks of surveillance.”

The proclamation claimed the explosion was caused by a 200 kilogram payload hidden at the site near the facility’s gas tanks. The tanks were intended to supply emergency power to the generators in case of electricity shortages.
