The new president means business, escalating the crisis with air strikes. Leedin no doubt about his new policy for the East. Kiev ordered a major assault to try to retake Donetsk airport from rebels who'd storm the terminal, perhaps knowing the president wanted to pay them a visit. He's now threatening to crush the pro-Russian militants who he refuses to negotiate with. They just marrador, they just abandoned, they just a killer, they just a terrorist. That's a case. And if you expect it, they will find out the support of these people, no way. The response from the separatists was swift. These pictures showed them fanning out through the city, taking their positions, on shore of what more Kiev is planning. A fighter who says he's with the Vostok battalion is asked what's happening. How many of you are there, says a reporter. Many he replies, but in spite of their bravado, the leader of the self-proclaimed republic is used a desperate appeal to the Russians for help. In connection with the latest developments which are unfolding so fast and so aggressively, we have to appeal to the Russian president, Vladimir Putin personally, and to the whole Russian people. Ukraine's president says his country must be unified, but he risks military involvement by the Russians, who earlier said they were open to dialogue. The people of the East may have voted for autonomy, but with civilians running for cover, escalation is something everyone now fears. We are trying to establish a dialogue between the powers to be in Kiev and all the regions of Ukraine, and we are convinced that this is a key issue in resolving the great crisis of Ukrainian statehood. Ukraine's president avoided a second round runoff giving him the mandate to talk tough, but this is what he faces. High stakes, knowing the separatists aren't alone force, with their declared allegiance to Moscow.
