(Reuters) -The Israeli military said it killed a Palestinian it accused of involvement in Hamas' October 7 attack on Israel in a vehicle strike in Gaza, and is investigating claims that the individual was an employee of aid group World Central Kitchen.

At least 25 Palestinians were killed in Israeli military strikes across Gaza overnight and into Saturday, with most casualties reported in northern areas, medics told Reuters.

Among those killed, at least seven died in an Israeli strike on a house in central Gaza City, according to a statement from the Gaza Civil Defense and the official Palestinian news agency WAFA early on Saturday.

The Gaza Civil Defense also reported that one of its officers was killed in attacks in northern Gaza's Jabalia, bringing the total number of civil defense workers killed since October 7, 2023, to 88.

Earlier on Saturday, WAFA reported that three employees of the World Central Kitchen, a U.S.-based, non-governmental humanitarian agency, were killed when a civilian vehicle was targeted in Khan Younis, southern Gaza.

The World Central Kitchen has not yet commented on the incident.
