The foreign ministers of Australia, Belgium, Malaysia, the Netherlands and Ukraine sent an open letter to the United Nations Security Council demanding to immediately set up an international criminal tribunal to bring to account those responsible for Malaysian Boeing flight MH17 disaster a year ago.

The Financial Times released the aforementioned letter on Friday.

"Our countries have asked the UN Security Council to swiftly establish an international criminal tribunal under Chapter VII of the UN Charter to try those responsible for this crime. Such a tribunal would ensure the highest levels of transparency, impartiality and accountability. It would deliver justice to the families of all victims of MH17," the edition quoted the ministers as saying.

The envoys of five states believe that safe air travel for all our citizens is essential to a peaceful world and the development of international relations.

"So we cannot allow an atrocious attack such as this to go unpunished. Impunity for the perpetrators would lead to unacceptable risks for the future," they said.

According to the document, such tribunal would ensure broad international support and maximize the potential for international cooperation.

"Moreover, this approach is consistent with international practice. All other ad hoc criminal courts and tribunals have been established prior to the completion of their respective criminal investigations," the foreign chiefs stressed.

They believe in future setting up of such kind of the tribunal would oblige all states to co-operate fully with the International Tribunal and its bodies.

The signatories of the letter are Ukrainian foreign chief Pavlo Klimkin and his colleagues from the Netherlands (Bert Koenders), Australia (Julie Bishop), Belgium (Didier Reynders), and Malaysia (Anifah Aman).

On July 17 2014, 298 passengers and crew were flying from Amsterdam to Kuala Lumpur on Malaysia Airlines flight MH17 when their plane was shot out of the sky.
