Commander of the Ukrainian Joint Forces Operation (JFO) Serhiy Nayev says Ukraine has no information about Russia's preparations for an attack in the south.

Yet, all types of intelligence collected on a daily basis have been beefed up, he said in a comment for the RBC Ukraine media outlet.

In addition, Ukrainian law-enforcement agencies checked out their interoperability and the heavy security was rolled out.

"We are clearly aware of all the scenarios that may develop in that sector and adequately assess the capabilities of the Russian Federation's Armed Forces for massing troops within a short period of time," he said.

According to Nayev, certain efforts to boost Ukrainian military units' combat capabilities in that sector have already been made and the work continues.

As UNIAN reported earlier, former Commanding General of United States Army Europe (Wiesbaden, Germany), Lieutenant General Ben Hodges warns that Russia may attack Ukraine's Kherson region in September under the pretext of military drills in order to secure the supply of drinking water for Russia-occupied Crimea, which is facing a critical fresh water shortage.
