US Vice President Kamala Harris faced some interruption from protesters opposing US support for Israel’s offensive in Gaza that has killed tens of thousands and caused a humanitarian crisis, Reuters reports.

Harris reiterated her support for a ceasefire and hostage rescue deal during her speech in Wilkes-Barre, Pennsylvania.

“Now is the time to get a hostage deal and ceasefire,” Harris said when interrupted. “I respect your voice, but right now, I am speaking,” she added.

Harris has pledged support for Israel. Observers have said that if pro-Palestinian Americans including activists as well as Muslims and Arabs, who overwhelmingly voted for the Democrats in the last presidential election, withhold their vote, it may hurt Harris’ chances.

While those groups are unlikely to tilt toward Donald Trump, some activists have pledged support to third-party candidates.
