The Russian Defense Ministry on Saturday ordered its troops to attack Ukraine in all directions "in response to Kyiv's refusal to negotiate."
Ministry spokesperson Igor Konashenkov said that as a result they will intensify the attacks, which began on Thursday, adding that six Ukrainian ships were sunk near the Snake Island in Black Sea by Russian army.
"US RQ-4 Global Hawk and MQ-9A Ripper strategical unmanned aerial vehicles were hovering in the provocation area when Ukrainian ships attacked Russian ships near Snake Island," he said.

"We call on to the people of Ukraine: demand from the criminal authorities in Kyiv to immediately remove all heavy weapons from their homes and residential areas of cities," he said.
"I would like to emphasise once again that the Russian armed forces did not hit any settlements in Ukrainian cities."
