The Israeli army arrested 180 displaced Palestinians from a school used as a shelter in the Jabalia refugee camp in the Gaza Strip, amid an ongoing military campaign in the camp, according to a prisoner group on Friday.

"The occupation forces arrested some 180 displaced from the Al-Harthani school in the northern Gaza Strip during ongoing aggression," the Prisoners Media Office NGO said in a statement.

The statement, however, did not provide details on how or which day the Palestinians were arrested.

Witnesses told Anadolu that the Israeli army targeted several shelters in the camp and arrested dozens of people.

On May 12, the army started a wide-scale military operation against the camp during which it destroyed homes and forced residents to flee areas in the camp.
