Sami Esmail, an Arab-American Michigan State University graduate student, was expelled from Israel yesterday after serving 10 months in prison on conviction of belonging to an Arab guerrilla organization.

Esmail, 24, who was paroled after serving two-thirds of his sentence, was arrested in December on his arrival in Israel to visit his dying father in Ramallah in the occupied West Bank.

Born in Brooklyn, N.Y., of Palestinian parents, Esmail was convicted of belonging to the Popular Front for the Liberation of Palestine and undergoing guerrilla training in Libya in 1976. Israel's District Court charged him with membership in the Popular Front because he distributed its newspapers on Michigan State's campus and contributed money to the organization.

Saunders, who is scheduled to leave Israel on Monday, said he also will meet West Bank political leaders, most of whom have publicy rejected the Camp David accords.

When he crossed into Israeli-held territory from Jordan over the Allenby Bridge, Saunders said: "We believe a moment of significant opportunity is available here for everyone involved in this process, and we would like to ensure that everyone understands exactly what those opportunities are so that no one will reject them out of misunderstanding or lack or knowledge of what is involved."
