KYIV (Reuters) - Russian forces used tear gas and stun grenades to disperse a pro-Ukraine rally in the occupied city of Kherson on Wednesday, Ukraine's Prosecutor General said, as Moscow tightened its grip over the southern Ukrainian region.

Local authorities say Russia appointed its own mayor of Kherson on Tuesday after its troops took over the administration headquarters in the regional capital, which was the first big urban centre to be seized after the Feb. 24 invasion.
