Arafat arrives in Jordan for talks with Hussein

Palestinian leader Yasser Arafat arrived in Amman for talks with Jordan's King Hussein. The talks are considered crucial in deciding a Jordanian response to President Reagan's Middle East peace plan. Mr. Arafat, chairman of the Palestine Liberation Organization, appears to have hardened his stance in advance of those talks, by rejecting the Reagan plan.

Meanwhile, Moroccan government sources said they were preparing for an Arab summit meeting in the eastern city of Fez on April 16 and 17. The topic: how to maintain Mideast peace momentum, the sources said.
