(Bloomberg) -- President Joe Biden travels to Israel with tensions high after an explosion at a Gaza hospital killed hundreds of people. Oil rallied following the blast and Arab leaders canceled a planned summit with Biden on Wednesday, complicating his push to contain a conflict that threatens to engulf the region.

Biden said he was “outraged and deeply saddened” by the explosion and added that he had asked “my national security team to continue gathering information about what exactly happened.” Hamas and Israel’s army traded accusations over who was to blame. 

Hamas — designated a terrorist group by the US and Europe — called it the result of an Israeli airstrike, while Israel’s army said the hospital was struck in a failed missile attack by Palestinian militants. Anti-Israel protests broke out in several major cities around the region.

Oil Rallies as Hospital Blast Ratchets Up Tensions (4:29 a.m.)

West Texas Intermediate rose above $88 a barrel after a deadly explosion at a Gaza hospital boosted tensions in the Middle East before President Joe Biden’s arrival in the region. Oil swung by more than $2 on Tuesday.

The global oil market has been rocked by the crisis. Traders are on alert in case the fighting spreads beyond Gaza, potentially embroiling Iran, which supports Hamas. A wider conflict could endanger crude flows, further tightening what was an already-stretched oil market following months of OPEC+ supply cuts. 

Iran has already warned of the scope for escalation of the conflict, saying earlier this week that such an outcome was becoming “inevitable.”

The decision to scrap Biden’s trip to Jordan was made after consulting with King Abdullah II of Jordan and in light of the days of mourning that Palestinian Authority President Mahmoud Abbas announced following an explosion at a Gaza hospital that killed hundreds of people, according to a White House official.

Jordan’s Foreign Minister Ayman Safadi announced earlier Tuesday said the proposed summit between Biden, Abdullah, Abbas and Egyptian President Abdel Fattah El-Sisi had been canceled, saying the decision was taken by mutual consent after reports that more than 500 people were killed in the blast at a hospital in Gaza.

Hundreds Killed in Gaza Hospital Strike (11:30 p.m.)

The Gaza Health Ministry said that at least 200 people had died in the hospital bombing. Officials from the ministry in the Hamas-run Palestinian territory told Al Jazeera television that the toll is 500, which would make it the deadliest attack since the Oct. 7 Hamas assault on Israel. 

The Israeli military said the hospital was hit in an attempted missile strike by a Gaza-based militant group. “The Islamic Jihad is responsible for the failed launch that hit the hospital,” the Israel Defense Forces said in a statement on X, formerly Twitter, citing intelligence from several sources. Turkey and Egypt were among countries to condemn the attack and blame Israel for it. The Pentagon said it didn’t immediately have information about who was responsible.

Israel’s issuer rating for long-term debt was placed on Rating Watch Negative by Fitch, signaling a possible cut in the nation’s A+ credit grade.
