U.S. Ambassador Nikki Haley slammed the United Nations on Tuesday for pushing an investigation into the measures Israel took to secure its border during violent clashes with Hamas-backed insurgents earlier this week. After she concluded her speech, she walked out of the chamber when a Palestinian representative began to speak.

For months, Palestinians have been protesting along the Gaza-Israeli border in objection to Israel’s 70 years in existence. Protestors have been reportedly burning tires in order to create a thick black cloud of smoke that obfuscates them and enables them to carry out acts of violence. Israel Defense Forces (IDF) say Hamas insurgents used the U.S.’s embassy relocation to Jerusalem as an excuse to storm the border and plant explosives. At least 58 Palestinians were killed yesterday, spurring the U.N. to propose investigating the IDF to determine if their actions violated international law — a proposal Haley slammed as preposterous.

“Who else would accept this type of activity on your border?” Haley asked the council. “Those who suggest the violence has anything to do with the U.S. location of the embassy are sorely mistaken.”

“Hamas maps and social media show the fastest routes to reach Israeli communities in case demonstrators make it through the security fence,” Haley said. “They have reported on Hamas messages over loudspeakers that urge demonstrators to burst through the fence, falsely claiming Israeli soldiers were fleeing, when in fact, they were not.”

She then walked out of the chamber as a Palestinian representative began speaking.
