(CN) — In a major diplomatic gamble, U.S. President Joe Biden stirred more tensions in the Middle East with a trip to Tel Aviv on Wednesday to show unflinching support for Israel, even as it carries out massive bombing of the Gaza Strip in retaliation for a horrific attack by Hamas.
Biden's trip was overshadowed by a strike on a Gaza hospital Tuesday evening that left hundreds of people killed, sparking widespread anger and protests in the Middle East and raising fears in Europe of terrorist attacks.
Israel and Hamas, the militant Palestinian group, blamed each other for the hospital strike with both sides presenting as yet unconvincing evidence. On Wednesday, authorities in Gaza said 471 people were killed in the blast at the al-Ahli al-Arabi Hospital.
In a news conference with Israeli Prime Minister Benjamin Netanyahu, Biden expressed full support for Israel and sided with Israel's version of what happened in the hospital explosion, which he said had made him “deeply saddened and outraged.”
“Based on what I’ve seen, it appears as though it was done by the other team, not you,” Biden said, sitting next to Netanyahu. “But there’s a lot of people out there not sure, so we’ve got to overcome a lot of things.”
The Israeli military contends a faulty rocket launched by Islamic Jihad, a Palestinian militant group, landed on the hospital. Hamas and Islamic Jihad said an Israeli missile was to blame.
The horrific scenes from the Gaza hospital fueled even more anger and protests across the Middle East and caused Jordan's King Abdullah II to cancel a summit in Amman on Wednesday with Biden. Egyptian President Abdel Fattah el-Sisi and Palestinian Authority President Mahmoud Abbas also were due to meet Biden in Amman.
Biden and the Arab leaders were slated to talk about ending the war and finding solutions to the growing humanitarian crisis in Gaza. Washington is trying to convince Egypt to open its border to people trapped in Gaza, but el-Sisi is reluctant to do that because he could come under criticism from other Arab nations and set in motion the displacement of Palestinians from Gaza to the Sinai Peninsula, which is part of Egypt.
Ayman Safadi, Jordan’s foreign minister, told a state-run television network that the war is “pushing the region to the brink.”
China and Russia, meanwhile, are pushing their own diplomatic talks with Arab leaders in an effort to counter American influence in the Middle East. On Wednesday in Beijing, Russian President Vladimir Putin met with Chinese President Xi Jinping, who was hosting a global development summit with numerous world leaders.
Beijing has refused to condemn Hamas and it has called for a cease-fire. China's influence in the region is growing after it brokered a deal in March between Saudi Arabia and Iran to reopen diplomatic ties.
On Monday, China was one of four countries that voted in favor of a Russian-drafted U.N. Security Council resolution urging a humanitarian cease-fire in the Israel-Hamas war. A similar Security Council resolution brought by Brazil on Wednesday was vetoed by the U.S. while the United Kingdom abstained.
After the hospital strike, United Nations Secretary-General António Guterres called for "an immediate humanitarian cease-fire" to ease "the epic human suffering."
"Too many lives — and the fate of the entire region — hang in the balance," Guterres said.
Across the Middle East, tensions are running very high and fears are growing that a regional war may erupt. The U.S. has sent two aircraft carrier strike groups to the Eastern Mediterranean and mobilized thousands of troops. The Pentagon says the aircraft carriers are stationed off the coast of Israel to deter Iran and Hezbollah from entering the conflict.
