A series of three assassination cases aimed at Russian officials in southern Ukraine is a testament.

On June 24, Dmitry Savluchenko, who was in charge of the youth and sports department in Kherson, died of a car with a bomb.

US officials said that there was no sequence of brain -headed brain -headed brain, but attacks occurred at a higher frequency.

Meanwhile, the Ukrainian forces are constantly counterattacking near Kherson, increasing pressure on Russia.

The Ukrainian battlefield situation after more than 4 months of fighting.

Leaders of this region are appointed by Moscow, saying they can organize a referendum to merge Russia in the second half of this year.

Kherson issued a Russian passport to the local people with the procedure of simplification under the decree of President Putin signed in May.

It is not clear how many Russian soldiers are stationed in Kherson, but to control the crowded areas of the local people with hostile psychology requires more force than controlling in peace, US officials said.

A source of Western intelligence said that the Ukrainian resistance in Kherson was not developed from small attacks to an organized campaign, capable of managing, providing weapons and planning.

However, in the long run, Russia may face a great counter -attack movement from the locals.

I think Russia will have a significant challenge when trying to establish any solid management form for these areas, because it is likely that those who cooperate with Russia will be assassinated, and others will be.

Ukrainian officials said Ihor Kolykhaiev, mayor of Kherson, was arrested by Russian forces for not cooperating.
