The United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) said Sunday that 69 percent of the Gaza Strip is under active Israeli displacement orders.

The Israeli army issued at least 20 displacement orders between March 18 and April 14, UNRWA said in a press statement, adding that the agency "currently operates 115 shelters across Gaza, housing more than 90,000 displaced people."

Some 420,000 people have been displaced again since the ceasefire collapsed on March 18, it said, warning that the already dire humanitarian situation in Gaza is worsening due to Israeli shelling and the seven-week-long aid blockade.

UNRWA stressed the need for an early ceasefire, the release of all hostages, and the unfettered flow of humanitarian aid and commercial supplies into Gaza.

Israel has blocked the entry of all humanitarian aid into Gaza since March 2. It then ended a two-month ceasefire with Hamas on March 18 and resumed deadly air and ground assaults on the enclave.

The renewed Israeli attacks have so far killed 1,827 Palestinians and injured 4,828 others, Gaza health authorities said Sunday, adding the death toll in the enclave since the war began in October 2023 has risen to 51,201, with 116,869 injured.
