Moscow : President Vladimir Putin said on Tuesday, that the peace talks with Ukraine had hit a dead end, using his first public comments on the conflict in more than a week to vow his troops would win and to goad the West for failing to bring Moscow to heel.

Addressing the war in public for the first time since Russian forces retreated from northern Ukraine after they were halted at the gates of Kyiv, Putin promised that Russia would achieve all of its "noble" aims in Ukraine.

In the strongest signal to date that the war will grind on for longer, Putin said Kyiv had derailed peace talks by staging what he said were fake claims of Russian war crimes and by demanding security guarantees to cover the whole of Ukraine.

"We have again returned to a dead-end situation for us," Putin, Russia's paramount leader since 1999, told a news briefing during a visit to the Vostochny Cosmodrome 3,450 miles (5,550 km) east of Moscow.
