US President Joe Biden said Monday that he was working to have Israel significantly reduce its military presence in Gaza, after being heckled by far-left protesters calling for a ceasefire in the Strip, during a speech at a church in South Carolina where a white supremacist killed nine Black worshipers in 2015.

“If you really care about the lives lost here… you should call for a ceasefire in Palestine,” a woman in the crowd could be heard interrupting the US president.
