Israeli Prime Minister Benjamin Netanyahu visited northern Gaza on Tuesday, vowing to intensify military operations against Hamas until "all war objectives are achieved."

Accompanied by Defense Minister Israel Katz and military chief Eyal Zamir, Netanyahu received a security briefing from commanders at the site, according to a statement from his office.

The visit came as Gaza-based health authorities reported that the death toll from the 18-month Israeli offensive had surpassed 51,000.

Netanyahu praised Israeli troops for what he called "a remarkable job" in the Gaza Strip and said Hamas would continue to "absorb more and more blows."

Defense Minister Katz echoed the remarks, saying the military would escalate its pressure on Hamas until the group agrees to release the hostages and is ultimately defeated.

Meanwhile, the Israeli military has been continuing its attacks on the Strip.

According to Gaza-based health authorities, an Israeli strike hit a gate of the hospital in Khan Younis's Mawasi area earlier in the day, killing at least one medic and injuring nine other patients and medics.

An Israeli military spokesperson told Xinhua the strike targeted "the head of a Hamas terrorist cell and a combat zone commander."

"The strike was conducted using precise munitions to mitigate harm in the area as much as possible," the spokesperson said.
