Hundreds likely dead in Gaza hospital blast, as Israeli blockade cripples medical response

Palestinian officials say hundreds were killed by a massive blast at a Gaza hospital on Tuesday, as humanitarian concerns mount over Israel's deprivation of food, fuel and electricity to the enclave's population.

Al-Ahli Baptist Hospital was sheltering thousands of displaced people when it was bombed Tuesday, the Palestinian Health Ministry said in a statement. Many victims are still under the rubble, it added.

Palestinian officials blamed ongoing Israeli airstrikes for the lethal incident. But the Israel Defense Forces has "categorically" denied any involvement in the hospital attack, blaming instead a "failed rocket launch" by the Palestinian Islamic Jihad group, a rival Islamist militant group in Gaza.

"We did not strike that, and that the intelligence that we have suggests that it was a failed rocket launch by the Islamic Jihad, and I want to add, categorically, that we do not intentionally strike any sensitive facilities, any sensitive facilities, and definitely not hospitals," Lt. Col. Jonathan Conricus told CNN.

Gaza has been under siege by Israel for more than a week, in response to the deadly incursion by Hamas, the Islamist militant group that controls the coastal enclave, home to 2.2 million people. Hospitals meanwhile are struggling to tend to the wounded across the territory, operating with shortages of electricity and water.

Vital humanitarian aid is meanwhile piling up at Gaza's shuttered border, despite diplomatic efforts to open a corridor from Egypt. The United Nations and other officials have said they need assurance of safe passage for any potential aid convoys.

Amid growing international pressure to address the crisis, US President Joe Biden will travel to Israel on Wednesday, an extraordinary wartime visit that follows intense efforts by Secretary of State Antony Blinken across the Middle East.
