After he speaks with Zelensky, Trump will have another important meeting – with Israel’s Benjamin Netanyahu. It is the first time the two have met in person since the war on Iran started in late February.

Zelensky and Netanyahu are in Washington to attend the funeral of Senator Lindsey Graham, who died this month aged 71.

The Ukraine war appeared to coincide with the US-Israel war with Iran at the weekend, when Ukrainian forces targeted an Iranian cargo ship in the Caspian Sea.

Kyiv has described Iran as a “direct accomplice to Russian aggression against Ukraine” and Zelensky has said Ukrainian intelligence has evidence that Russia has shared satellite imagery with Tehran, enabling Iran to attack US military facilities and Gulf states.

Trump has said he will “find out if that’s true. I’ll ask Putin about it”, while saying if true, it had no impact at all.

Meanwhile, in Moscow, Mayor Sergei Sobyanin said more than 390 Ukrainian drones had targeted the region between 20:30 on Monday and 06:30 on Tuesday local time, and that most had been intercepted by air defences.

Footage confirmed by BBC Verify showed damage to a high-rise building in Chekhov, south of the capital and a fire at a warehouse in Berezhki to the west. Local officials in Chekhov said there had been no casualties.

Since Zelensky last spoke to Trump in early July, Ukraine has repeatedly targeted logistics hubs, many belonging to Russian e-commerce company Wildberries, exacerbating issues faced by small and medium-sized business in parts of Russia.
