UNITED NATIONS (AP) — Palestinian President Mahmoud Abbas accused Israel of ethnic cleansing Thursday for building settlements in east Jerusalem.

“It is a campaign of ethnic cleansing against the Palestinian people via the demolition of their homes,” Abbas said in his speech to the U.N. General Assembly.

Shortly after, Israel Prime Minister Benjamin Netanyahu rebuked Abbas in his own address.

“We won’t solve our conflict with libelous speeches at the U.N.,” Netanyahu said.
