The Wall Street Journal reported that Russia targeted on Wednesday a military base in Ukraine, using the Iranian "Shahed-136" unmanned aircraft, which poses an increasing challenge to Kiev, in the face of the drone force. 

Ukraine reported receiving a wave of Russian attacks with Shahed-136 aircraft in the past three weeks, the Journal reported but targeting the Bila Tserkva area redressed the balance, which is the closest attack to the capital, Kiev, using this weapon.

For his part, Oleksiy Kuleba, head of the regional military administration in Kiev, said that six explosions were heard during the night in Bila Tserkva, about 50 miles south of the Ukrainian capital, stressing that the attack was carried out by the Iranian-made "Shahed 136 Delta" drones. 

Smoke and flames rose from the base housing the Ukrainian "72" Brigade, which fought in Kiev in the early days of the war and is now fighting in the eastern city of Pakhmut.

The newspaper reported that dozens of soldiers in uniform, including some who claimed they had recently returned from fighting in eastern Ukraine, gathered in groups on nearby streets. They said their barracks had been destroyed and that they were waiting for orders to see where they were going now.

The drone attack began around 1:30 am local time, and as the explosions sounded louder, some soldiers rushed from the barracks to race toward their basement shelters.

Politico reported in a previous report on the Ukrainian military that Iranian drones may change the rules of the game for the Russians, as they pose a major threat to the Ukrainian army.
