BEIRUT, Lebanon (AP) _ Assailants protesting Russia's crackdown on Chechnya fired rocket-propelled grenades Monday at the Russian Embassy in Beirut, killing a policeman. Troops killed one attacker during a manhunt.

No Russian casualties were reported at the embassy, located along the busy Corniche Mazraa thoroughfare, but political attache Andrey Avdeev said the building's consular area was damaged.

There was no claim of responsibility for the attack, but the Mazraa area is in the Muslim sector of Beirut, where extremists are sympathetic to fellow Muslims in Chechnya. Lebanese Muslim militants opposed to Russia's military campaign in the breakaway republic have staged protests and have been raising money for the Chechens.

Police sources confirmed, on condition of anonymity, reports that the dead assailant was carrying a statement indicating the attack was motivated by anger with Russian military actions in Chechnya.

State-run television reported the paper said: ``In sacrifice for Chechnya.'' A private radio station, Voice of Free Lebanon, said the paper found on Kharroub was addressed ``The Call of Grozny.''

Lebanese army troops and police in armored personnel carriers and trucks fanned out in the area shortly after the midday attack, which shattered windows and left the compound pocked with shrapnel and bullet marks. The windshield of an embassy car was shattered.

The assailants launched four grenades and fired assault rifles at the embassy from a nearby building. Security forces stormed the building and killed one of the attackers, police said. Several passers-by were injured in the chaos.

Troops sealed off neighboring buildings and streets and searched for at least two assailants who fled under heavy rain.

It was the most serious attack on a foreign diplomatic mission in Lebanon since the end of the 1975-1990 civil war, during which foreign nationals and embassies as well as ordinary Lebanese were targets of armed factions.

Officials at the Russian Foreign Ministry gave no immediate comment on the attack. The Interfax news agency quoted the ministry as saying only that ``details of the occurrence are being clarified.''

In Shepherdstown, W.Va., where Israel and Syria were resuming peace talks, State Department spokesman James P. Rubin condemned the attack on the embassy, calling it a ``cowardly act of terrorism.''

Police identified the dead suspect as Ahmed Raja Abou Kharroub, a 30-year-old Palestinian resident of Ein el-Hilweh, Lebanon's largest Palestinian refugee camp. Ein el-Hilweh, located outside the port city of Sidon, 30 miles south of Beirut, is a camp of 75,000 controlled by rival Palestinian factions, including radical groups and the PLO's mainstream Fatah group.

Police did not say whether Abou Kharroub was known to be affiliated with any particular group.

Later Monday night, assailants threw a small explosive at an army checkpoint on the edge of the Ein el-Hilweh camp, causing no casualties or damage, Lebanese security officials said. It was not clear if the bomb was meant to avenge Abou Kharroub's death.

Russian troops launched a military offensive in September to wrest control of the rebel republic of Chechnya after Chechen-based militants invaded a neighboring region and were blamed for bombings elsewhere in Russia.
