A Japanese Red Army member, who will be sentenced here Monday for pos session of high- powered bombs, was part of a plot to avenge the 1986 U.S. bombing of Libya, according to court papers released here.

The papers, a prosecution pre-sentencing report released Friday, said that Yu Kikumura, 34, planned to explode pipe bombs at a New York City naval recruiting station on April 14, 1988 - the second anniversary of the U.S. bombing of Libya.The papers said the bombs could have injured dozens of people.

Prosecutors said Kikumura's attack was meant to coincide with the April 14, 1988, bombing of an American serviceman's club in Naples, Italy, in which five people died.

The pre-sentencing report quoted a secret informant as saying that Kikumura and other members of the left-wing Japanese extremist group were trained at a camp for "terrorists" in Lebanon's Bekaa Valley.

According to the informant, Kikumura trained with Junzo Okudaira at the camp. Okudaira is a Red Army member who is a prime suspect in the Naples bombing.

The pre-sentencing report asked that Kikumura be jailed until he is too old to make bombs.

Kikumura, who was arrested on April 12, 1988, at a rest stop on the New Jersey Turnpike after acting suspiciously, could receive up to 100 years in prison.

Three pipe bombs and bomb-making equipment were found in his car. Prosecutors say Kikumura was en route to Manhattan.

Attorneys for him deny that he planned to hurt or injure people, although they admit he was in possession of the bombs.

Prosecutor John Lacey, an assistant U.S. attorney, said no allegations were made that Libya was behind the revenge plot.

"We do not contend that the Libyan government or Moammar Gadhafi is behind this," he said.

Kikumura spent four weeks traveling the country, going to 17 states to assemble the parts for the bombs, the report said.
