The Russian army moved with ease in the wide open spaces of northern Chechnya and reached the Terek River on 5 October 1999. On this day, a bus filled with refugees was reportedly hit by a Russian tank shell, killing at least 11 civilians; two days later, Russian Su-24 fighter bombers dropped cluster bombs on the village of Elistanzhi, killing some 35 people. On 10 October 1999, Maskhadov outlined a peace plan offering a crackdown on renegade warlords; the offer was rejected by the Russian side. He also appealed to NATO to help end fighting between his forces and Russian troops, without effect.
