GAZA CITY, Palestinian Territories: Dozens of Palestinians gathered at a Gaza City hospital on Saturday to mourn six people, including children, that the civil defense said were killed by the Israeli shelling of a shelter for displaced people.

The Israeli military said late on Friday that troops had fired at “suspicious individuals to eliminate the threat,” adding that it was reviewing the incident and “regrets any harm to uninvolved individuals.”

Gaza’s civil defense agency, which operates as a rescue force under Hamas authority, initially said on Friday that the Israeli shelling of a school-turned-shelter killed five people in the Tuffah neighborhood east of Gaza City.

Agency spokesman Mahmud Bassal updated the toll to six, including children, on Saturday, adding that two people were unaccounted for under the rubble.

The director of Gaza City’s Al-Shifa Hospital, Mohammed Abu Salmiya, told AFP the victims were a four-month old infant, a 14-year-old girl, two men and two women.
