RAMALLAH, West Bank (AP) — Palestinians have denounced reported U.S. attempts to undercut a U.N. agency that serves several million Palestinian refugees and their descendants.

The U.S.-based Foreign Policy magazine has reported that Jared Kushner, Mideast adviser to President Donald Trump, called in an email this year for a "sincere effort to disrupt" the agency.

In previous U.S.-led negotiations, the fate of Palestinian refugees and contested Jerusalem were to be settled in a peace deal. Palestinian officials now fear that the Trump administration is moving unilaterally to settle these issues in Israel's favor.

Nabil Shaath, an adviser to Palestinian President Mahmoud Abbas, alleged Sunday that the Trump administration is "pushing to impose facts on the ground, by realizing all of Israel's demands."

Abbas' office said Saturday it would "foil conspiracies to end the Palestinian cause."
