In Thursday comments President Trump condemned what he called Russia's "disgusting" strikes on the Ukrainian capital from the night prior, which left 28 dead according to the continually rising death toll, after emergency crews have been picking through rubble of a collapsed apartment building.

The Trump administration has also informed the UN Security Council that a deal needs to be reached by August 8, or else new tariffs and sanctions targeting Russia and its trading partners will be unleashed.

"Both Russia and Ukraine must negotiate a ceasefire and durable peace. It is time to make a deal. President Trump has made clear this must be done by August 8. The United States is prepared to implement additional measures to secure peace," US diplomat John Kelley told the UN Security Council, according to Reuters.
