Teams of Ukrainian military experts have been sent to Qatar, the United Arab Emirates and Saudi Arabia to help them defend against drones being launched from Iran in retaliation for the massive US and Israeli air attacks.

Others are also helping the US defend its military presence in Jordan, according to Ukrainian President Volodymyr Zelensky.

In a video address, Zelensky said Ukraine had "the greatest experience in the world in countering attack drones" – a reference to expertise built up over the more than four years of attacks by Russia on its neighbour.

Ukraine says the US and 10 more countries across the Middle East and Europe have asked for help countering the threat of drones that have wrought much damage.

There has been no comment by any of the countries concerned. Last week President Trump said he would take help from "any country" that offered it, including Ukraine.
