Sporadic clashes marked the end of a truce in breakaway Chechnya, but there was no resumption of large-scale fighting and the sides were reported consulting on a new round of peace talks.

Heavy explosions were heard every few minutes in the town of Goyity, 10 miles south of the Chechen capital, Grozny, after the truce expired at sunset Sunday. It was unclear which side fired.Despite accusations by each side that the other had violated the five-day truce, Interfax said Russian and Chechen representatives were in telephone contact earlier Sunday to determine if and when talks should be resumed.

A military aide to Chechen leader Dzhokhar Dudayev, Musa Mer-zhuyev, said even "this illusory chance" should not be wasted.

And Prime Minister Viktor Chernomyrdin of Russia said Sunday that Moscow wants to pursue peace talks.

"The bloodshed must be stopped and everything must be solved by political methods, not force," ITAR-Tass quoted Chernomyrdin as saying as he returned from a visit to Poland.

Russia's proposals to end the 10-week-old war have amounted to virtual demands for Chechen disarmament. Dudayev has been no more flexible, saying that he is "unconditionally" ready for peace - except for the condition that Russia withdraw its troops.

Moscow's government news service said the Chechens breached the truce with an attempt to force their way into downtown Grozny on Saturday night and with attacks on Russian positions in the city's southern outskirts.

It said Russian forces "blocked and eliminated" 80 Chechen fighters who attempted an assault from the south, using mortars, grenade launchers and small arms.

Meanwhile, Dudayev's military aide, Merzhuyev, told Interfax the Russians violated the cease-fire by repeated artillery bombardments.

Many of the city's 400,000 residents have fled since the Kremlin sent its troops into Chechnya on Dec. 11 - and especially since the Russians first tried to storm Grozny on Dec. 31.
