The long-range Tomahawk missiles would boost Ukraine’s ability to strike targets deep inside Russia

We don’t know exactly what Trump and Putin are discussing, but their call comes just days after officials in Moscow raised concerns about the US potentially supplying long-range Tomahawk missiles to Ukraine.

When reporters asked Trump if he would provide Kyiv with Tomahawks on Sunday, he replied: “We’ll see… I may.” The missiles would be “a new step of aggression” in Ukraine’s war with Russia, he added.

Kremlin spokesman Dmitry Peskov said the topic of Tomahawks was of “extreme concern” to Russia, adding that “tensions are escalating from all sides”.

He said that if Tomahawks were launched at Russia, Moscow would not be able to tell whether they were carrying nuclear warheads.

“What should the Russian Federation think? Just how should Russia react?” he said.
