Putin will seek revenge for Ukraine drone attack, warns Trump

Vladimir Putin has said he will have to respond to Ukraine's major drone attack on Russian airbases, US President Donald Trump has warned.

Speaking after a phone call with the Russian president, Trump said: "President Putin did say, and very strongly, that he will have to respond to the recent attack on the airfields."

Trump warned in a social media post that the phone call, which lasted more than an hour, would not "lead to immediate peace" between Russia and Ukraine.

The two leaders also discussed Iran, with Trump saying Putin suggested he could help with nuclear talks with the country.

The White House has been approached for comment.

Russia's RIA Novosti, a state-owned news agency, said Putin told Trump that Ukraine has tried to "disrupt" the negotiations and that the government in Kyiv has "essentially turned into a terrorist organisation".

The two also "exchanged views on the prospects for restoring cooperation between the countries, which has enormous potential," it said.

The conversation between the two leaders marks the first since Ukraine launched a surprise attack using smuggled drones to strike Russian airbases on 1 June, targeting what it said were nuclear-capable long-range bombers.
