Poltorak: 42,5 thousands of Russian soldiers and rebels fighting in the ATO area
According to the Minister of Defence, approximately 42,500 Russian soldiers and insurgents are fighting in Donbass at present, with Russia being the main supporter of the armed conflict in the east of Ukraine.
He also added that Moscow continues to supply weapons and train rebel groups. It should be recalled that all foreign armed forces were to leave eastern Ukraine in accordance with the Minsk agreement.
"As of today, the total number of Russian armed forces and illegal armed units deployed to the occupied territories of the Donetsk and Lugansk regions accounts for app. 42,500 people," Poltorak said.
"They have 558 tanks, AVCs, MLRSs and other weapons. It would be enough for the average European country."
White House: US not to provide Ukraine with lethal weapons
The United States is not intending to supply offensive weapons to Kiev, as it would not contribute to solution of the crisis in the country, White House Press Secretary Joshua Earnest said. Earnest reminded that Washington had already provided Kiev with military assistance, reflecting the "depth of the US commitment to Ukraine." On May 15, US Congress passed a defence budget bill that will allocate $300 million in lethal defensive weapons for Ukraine government forces. US President Barack Obama has been reluctant to provide such assistance to Kiev. In March, Washington said it would redeploy up to 300 military instructors from Italy to Yavoriv, near the Polish border, as part of a mission to train the Ukrainian National Guard.

As reported earlier, a similar device was recently washed ashore by the sea near the village of Vynogradne. A fisherman who found it and tried to take it apart got wounded. Both explosive devices had drifted from rebel-held territories of Donbass, the press service announced.
