Nato is to deploy its forces at new bases in eastern Europe for the first time, in response to the Ukraine crisis and in an attempt to deter Vladimir Putin from causing trouble in the former Soviet Baltic republics, according to its chief.
Anders Fogh Rasmussen, the former prime minister of Denmark, said that next week's Nato summit in Cardiff would overcome divisions within the alliance and agree to new deployments on Russia's borders – a move certain to trigger a strong reaction from Moscow.
Ukraine's president, Petro Poroshenko, is to attend the Cardiff summit and will be the sole non-Nato head of state to negotiate with alliance leaders.
Asked whether there would be permanent international deployments under a Nato flag in east Europe, Rasmussen said: "The brief answer is yes. To prevent misunderstanding I use the phrase 'for as long as necessary'. Our eastern allies will be satisfied when they see what is actually in the readiness action plan."
Rasmussen said the forces could be deployed within hours.
