US President Donald Trump is considering sending Tomahawk long-range cruise missiles to Ukraine, saying it would provide a new step of aggression in its war with Russia.

When asked on Air Force One if he would send Tomahawks to Ukraine, Trump replied we'll see... I may.

This follows a second phone call at the weekend between Trump and Ukrainian President Volodymyr Zelensky, who pushed for stronger military capabilities to launch counter-attacks against Russia.

Moscow has previously warned Washington against providing long-range missiles to Kyiv, saying it would cause a major escalation in the conflict and strain US-Russian relations.

Tomahawk missiles have a range of 2,500 km (1,500 miles), which would put Moscow within reach for Ukraine.

Trump spoke to reporters as he flew to Israel. He said he would possibly speak to Russia about the Tomahawks requested by Ukraine. I might tell them [Russia] that if the war is not settled, that we may very well, we may not, but we may do it, Trump stated.

Kyiv has made multiple requests for long-range missiles, as it weighs up striking Russian cities far from the front lines of the ongoing conflict.

In their phone calls, Zelensky and Trump discussed Ukraine's bid to strengthen its military capabilities, including boosting air defenses and long-range arms.

Ukrainian cities including Kyiv have come under repeated heavy Russian bombardment, particularly targeting energy infrastructure and causing power cuts.

Last month, Trump's special envoy to Ukraine Keith Kellogg suggested the US president had authorized strikes deep into Russian territory, stating that there are no such things as sanctuaries in the Russia-Ukraine war.

Despite these developments, Russia downplayed the chances of Tomahawks changing the course of the war, with Kremlin spokesperson Dmitry Peskov claiming, Whether it's Tomahawks or other missiles, they won't be able to change the dynamic.
