UN calls Gaza one of world's "most dangerous" places as refugee camp hit by alleged IDF strikes. Catch up here

There are reports of a high number of casualties overnight after the Israeli military launched strikes on targets in and around the Jabalya refugee camp in northern Gaza.

The reports cannot be substantiated because access to the area is challenging and communications are poor. The alleged strikes come as the UN's main agency operating in Gaza said the enclave has now become "one of the most dangerous places in the world."

The United Nations Relief and Works Agency for Palestine Refugees in the Near East said the situation was "getting worse each minute" with a new wave of refugees in the south displaced by Israeli bombardment on Wednesday.

CNN has reached out to the Israel Defense Forces for comment on its operations in the Jabalya area.

Here are today's main headlines:

• Refugee camp struck: The Palestinian official news agency WAFA quoted witnesses as saying that the Israeli military “targeted an entire residential square in 'Block 2' in Jabalya camp, killing and wounding dozens, including children and women.” CNN cannot independently verify the reports because of challenges with access and lack of communications in the area.
• Death toll in Gaza surpasses 16,000: The Palestinian Health Ministry has reported that as of Tuesday, more than 16,000 people have been killed in Israeli attacks in Gaza since October 7. In its latest update on the health situation of Gazans, the ministry said about 41,000 people had been wounded, with thousands more thought to be missing or buried under rubble. The ministry, based in Ramallah in the West Bank, compiles its reports with data from hospitals in Hamas-run Gaza.
• Targets hit: Israel's air force struck about 250 Hamas targets in Gaza over the past 24 hours as troops continued to locate the militant group's weapons, underground shafts, explosives and military infrastructure, the Israeli military has said.
• Weapons found: The IDF claimed it found a large weapons stockpile near a clinic and school in northern Gaza. It said the weapons cache “contained hundreds of missiles and RPG (rocket-propelled grenade) launchers of various types, dozens of anti-tank missiles, dozens of explosive charges, long-range missiles aimed at the center of the State of Israel, dozens of grenades and unmanned aerial vehicles.” CNN cannot independently verify its claims or whether the weapons stockpile exists.
• Humanitarian organizations call for an end to attacks: In addition to UNRWA noting the danger to life in the Gaza Strip, humanitarian organization Médecins Sans Frontières (Doctors Without Borders) called for an immediate end to "indiscriminate and relentless attacks," on Gaza. They also said medical supplies were critically low at central Gaza's Al-Aqsa Martyrs Hospital.
• 76-year-old hostage in critical condition: The daughter of an elderly Israeli woman who was released after being held hostage in Gaza says her mother’s condition is “serious” and that she has been hospitalized again. Carmit Palty Katzir, daughter of 76-year-old Hana Katzir, told Israel Army Radio (GLZ) that “my mother is hospitalized in serious condition.
