The war ravages and lack of economic opportunities left numbers of armed former guerrillas with no occupation but further violence. Machine guns and grenades were sold openly and legally in Grozny's central bazaar. The years of independence had some political violence as well. On 10 December Mansur Tagirov, Chechnya's top prosecutor, disappeared while returning to Grozny. On 21 June the Chechen security chief and a guerrilla commander fatally shot each other in an argument. The internal violence in Chechnya peaked on 16 July 1998, when fighting broke out between Maskhadov's National Guard force led by Sulim Yamadayev (who joined pro-Moscow forces in the second war) and militants in the town of Gudermes; over 50 people were reported killed and the state of emergency was declared in Chechnya.
