European leaders will visit the United States on Monday or Tuesday to discuss ways to end the war in Ukraine, Donald Trump has said.

The US president added that he would also speak to Russian President Vladimir Putin 'soon', as well as signaling that his administration was ready to move to a second phase of sanctions on Moscow.

Ukrainian President Volodymyr Zelensky said the sanctions were the 'right idea', and urged European nations to stop buying Russian energy.

This comes as Russia launched its largest aerial bombardment on Ukraine of the war thus far, resulting in casualties and hitting the government's main building in Kyiv for the first time.

After the attack, during which Russia fired at least 810 drones and 13 missiles at Ukraine, Trump expressed his dissatisfaction with the situation.

'Certain European leaders are coming over to our country on Monday or Tuesday individually,' Trump mentioned, though it was unclear who he was referring to.

Heightened Russian attacks have been noted since Trump and Putin's recent summit in Alaska.

In a recent interview, Zelensky commented on the unfair nature of European dependence on Russian energy, stating: 'We must stop [buying] any kind of energy from Russia'.

Zelensky supported Trump's proposed secondary tariffs on countries trading with Russia, indicating they could diminish Moscow's war funding capabilities.

To date, Russia has amassed significant revenue from oil and gas sales since its invasion of Ukraine in March 2022, with significant buyers including China and India.

The EU is working to cease all energy imports from Russia by 2027, yet has not entirely halted purchases.

Recently, the US imposed a 50% tariff on goods from India as a punitive measure for its continued trade with Moscow, while India's government insists on securing favorable oil prices for its citizens.

Russia has also committed to escalating gas supplies to China as OPEC+ seeks to increase oil production amid fluctuating global prices.

US Treasury Secretary Scott Bessent is advocating for increased EU collaboration on implementing secondary tariffs against countries buying Russian oil, emphasizing that this could force President Putin to negotiate.

The current geopolitical dynamics in the region underscore a critical balancing act between sustaining Ukrainian military efforts and undermining the Russian economy.
