Ukraine unveils 600-mile cruise missile that can reach Moscow amid peace talks

"We have significant results," Zelenskyy said Saturday. "Long Neptune has been tested and successfully used in combat. A new Ukrainian missile, an accurate strike. The range is a thousand kilometers," or 620 miles. 

That puts Moscow within striking range. 

The refinery is under 60 miles from Russian President Vladimir Putin's sprawling cliffside palace on the Black Sea in Gelendzhik. 

The Neptune cruise missile was used in April 2022 to take out a flagship of Russia's Black Sea fleet. 

Zelenskyy has already agreed to the terms of a 30-day ceasefire after meetings with U.S. officials in Saudi Arabia. 

"We'll be talking about land, we'll be talking about power plants, that's a big question. But I think we have a lot of it already discussed, very much, by both sides, Ukraine and Russia," Trump said of his call. 

Russia has not accepted the terms of the ceasefire and accelerated attacks on Ukraine after Zelenskyy said he would agree to it.
