Israel launched “extensive” new ground operations in the Gaza Strip, while airstrikes in a new offensive killed at least 103 people, hospitals and medics said, and forced northern Gaza’s main hospital to close.

Israeli forces have besieged a hospital in northern Gaza as they continue an offensive to seize territory in the strip, the Hamas-run health ministry has said. Medical staff and patients at the Indonesian hospital, in Beit Lahia, came under "heavy fire... preventing the arrival of patients, medical staff, and supplies", the ministry said on Sunday.

Israel has begun its expansion of its ground offensive in the war-ravaged strip, as Palestinian health authorities say more than 460 people have been killed in the last week.
