With the crash of flight MH17 on Ukrainian territory, much attention is now on the response of the Ukrainian government. Since the disaster, Kyiv has branded the incident a ‘terrorist attack’, today the country’s Prime Minister, Arseniy Yatsenyuk further detailed Ukraine’s position, saying:

“ We ask all respective governments to participate in this investigation and to support the Ukrainian government to bring to justice all these b*****ds who committed this international crime. This is the crime against humanity. All red lines have been already crossed “

The focus of international efforts now centres around how the passenger plane was downed. Kyiv has insisted this was the doing of pro-Russian rebels using advanced Russian missiles.

In a bid to strengthen their case, they’ve released recordings claiming to be between a separatist from Donetsk and a senior member of the Russian military.

Valentyn Nalyvaychenko, the head of Ukraine’s security service said this about the alleged phone call: “We have shown how missiles called “Buk” crossed the Ukrainian border shortly before the terrorist attack . These talks show that terrorists themselves confirm getting these missiles from Russia ”

A transcript of the leaked call appears to detail the following conversation:

1) Hello, Buryat
(2) Hello, Nikolaevich, where should we take this beauty?
(1) Which one? The one…
(2) Yes, the one that I brought. I’m already in Donetsk
(1) Is this the one I’m thinking? “B”.. “M”?
(2) Yes, its “Buk”
