PARIS (AP) _ A Paris court today ordered Georges Ibrahim Abdallah to stand trial in the killings of a U.S. military attache and an Israeli diplomat in 1982.

No trial date was set, but court sources said it could begin in about a month. The order for a trial was made by the Chamber of Accusation of the Paris Court of Appeals, which heard arguments in the case Jan. 20.

Five terrorist bombings in September that were claimed by a group calling itself the Committee of Solidarity with Arab and Middle East Political Prisoners were aimed at forcing Abdallah's release. Ten people were killed and 162 injured.

Abdallah, presumed leader of the Lebanese Armed Revolutionary Factions, is serving a four-year term in Lyon on a conviction for possession of arms, explosives and false documents. He was arrested in October 1984 in Lyon.

In the present case, Abdallah is charged with complicity and attempted murder by instigation, aid and assistance in the slayings of Lt. Col. Charles Robert Ray, the military attache at the U.S. Embassy in Paris, on Jan. 18, 1982, and Israeli diplomat Yacov Barsimentov on April 3, 1982.

He also is charged with the attempted murder of Robert Onan Homme, the American consul in Strasbourg on March 26, 1984.

Another Lebanese, Jacqueline Esber, who is at large, also was ordered tried for murder, attempted murder and complicity in the Barsimentov and Homme cases.

Abdallah will be tried by a special court created to deal with terrorism cases and made up of seven magistrates.
