Volodymyr Zelensky has accused Vladimir Putin of trying to trick Donald Trump, and has called for allies to use force against Russia. 

He said Trump gave far too many concessions to Putin at their meeting in Alaska last month.

The Ukrainian leader told Sky News: 'I think it gave a lot to Putin. And I believe, if it was a trilateral meeting [with Ukraine included], we would have some result.'

During the Alaska summit, Putin reportedly told Trump that he wanted the eastern eastern Donetsk and Luhansk regions, for which he would give up some Ukrainian territory held by Russian forces. 

Zelensky said: 'He should have received a setback in this war and stop. But instead, he received de-isolation. He got the photos with President Trump.

'He received public dialogue, and I think this opens the doors for Putin into some other summits and formats, because that's how it is, and we see that, we observe this, and I don't think he paid anything for it.'

Zelensky said he wanted to see Ukraine's allies to properly fight back against Russia. 

'[Putin] is waging the war and everyone is trying to stop him by arguing, by asking him. But instead, force should be used. He understands force. That's his language, that's the language he understands - he doesn't speak many languages, but that's the language of force he understands, just like Russian: his mother tongue.

'And we ask European countries and the US to do that. Yes, they take steps such as sanctions, but more needs to be done quicker.' 

It comes as Ukrainian officials revealed Russian strikes have killed two people and wounded at least nine others. 

Ivan Fedorov, the head of the military administration in southeastern Ukraine's Zaporizhzhia region, said a Russian attack had left one person dead and nine wounded, including a child.

The governor of the southern Mykolaiv region, Vitaliy Kim, said Russian troops had attacked a farm there, killing a tractor driver as he worked in the field.

'This was a targeted attack on civilians,' Kim wrote on the Telegram social media platform.

Hopes of reaching a truce in the conflict have dimmed since US President Donald Trump held high-profile talks separately with his Russian counterpart Vladimir Putin and Ukraine's Volodymyr Zelensky last month.

Tensions have risen further since two NATO members, Poland and Romania, accused Russia of sending drones into their airspace, ostensibly as part of its attacks on Ukraine.

The alleged incursions prompted both countries to scramble fighter jets and Poland to close its border with Belarus, Moscow's staunch ally, while Minsk held military drills alongside Russian troops.

Moscow has brushed off the accusations, saying neither Poland nor Romania have presented convincing evidence that the drones were Russian, and calling the latter incident a 'provocation' by Ukraine.
