Student leaders said yesterday that they do not anticipate any demonstrations today.

"As far as I know, no formal organization is planning a demonstration," said Ethan M. Tucker '97, chair of Harvard-Radcliffe Hillel, who is a Crimson editor.

Yuval Segal '97, chair of Harvard Students for Israel, echoed Tucker's remarks, saying he knew of no protests in the making.

But security officials say they are "prepared for anything."

"Obviously security will be high, and I expect they will be prepared for anything, but there have been no indications of any [disturbances]," said Steven R. Singer, director of communications and public affairs for the Kennedy School.

According to Singer, Arafat's address will probably deal with Middle East peace issues.

"[His talk will be on] the Middle East peace process and where it goes from here, [and] the Palestinian perspective on the peace process and the future of the West Bank and the Gaza Strip," Singer said.

Arafat is speaking in only two cities in the United States. On Sunday, he delivered an address to the United Nations as part of the United Nations' 50th anniversary celebration. He will address the Council on Foreign Relations in New York City this morning before coming to Boston tonight.

"Harvard is very fortunate to be able to attract figures like Arafat and [Israeli Prime Minister Yitzhak] Rabin," Campion said.

Rabin is scheduled to speak at the IOP in mid-November.

Arafat's address and a short question-and-answer session will be followed by an invitation-only reception. Arafat will fly back to the Middle East immediately afterwards.

For those unable to obtain seats in the Arco Forum, the speech will be broadcast live via closed-circuit television to the Wiener Auditorium at the Kennedy School, Austin North at the Law School and Piper Auditorium at the Harvard Graduate School of Design. No tickets are necessary to attend these screenings. The forum will also be televised live on New England Cable News (channel 26 in Cambridge)
