Hundreds of Lebanese protesters, including some waving Palestinian flags, swarmed the US embassy in Beirut Tuesday evening in response to the massive blast at a Gaza City hospital that reportedly killed hundreds of people.

Police had to deploy tear gas to disperse the demonstrators who gathered outside the embassy hours ahead of President Biden’s arrival in neighboring Israel to show support for the Jewish state in its conflict with the terrorist group Hamas.

One protester was seen on video posted to social media scaling a barbed-wire fence surrounding the building in order to plant a Palestinian flag on the embassy’s flagpole as fellow ralliers cheered him on from below.

Elsewhere in Beirut, protesters descended on the French embassy.

The dual demonstrations came just hours after Lebanon-based terror group Hezbollah called for “a day of unprecedented anger” in Beirut after the deadly explosion at the Gaza medical center.

The Hamas-run Health Ministry has claimed Israel was responsible for the hospital blast, while the Israel Defense Forces blamed a failed Hamas rocket for the carnage that Gaza authorities said left 500 dead.

The strike marks the deadliest single incident during Israel‘s war against Hamas, which broke out after the terrorist group invaded the Jewish state on Oct. 7 and slaughtered at least 1,400 people.

Meanwhile, Biden’s trip to Tel Aviv originally included a stop in Amman, Jordan until the nation’s government canceled in light of the Gaza City attack.

“After consulting with King Abdullah II of Jordan and in light of the days of mourning announced by President Abbas of the Palestinian Authority, President Biden will postpone his travel to Jordan and the planned meeting with these two leaders and President Sisi of Egypt,” the White House said in a statement.

“The president sent his deepest condolences for the innocent lives lost in the hospital explosion in Gaza and wished a speedy recovery to the wounded. He looks forward to consulting in person with these leaders soon, and agreed to remain regularly and directly engaged with each of them over the coming days.”

Earlier Monday, the IDF ordered people living in 28 communities near the Lebanese border to evacuate.

Hezbollah has not said whether it would go to war with Israel, though the two countries have launched several attacks on one another since the Israel-Hamas conflict began last week.

The World Health Organization said Monday it has sent two shipments of medical supplies to Beirut in preparation for potential escalation along the Lebanon-Israel border.
