Crimean authorities have responded to Ukrainian President Petro Poroshenko's assertion today that "Crimea was and will again be Ukrainian".

Crimean Prime Minister Sergey Aksyonov said: "Crimea will never be part of Ukraine. That phase, undoubtedly, has passed"- he said.

He added that Crimea has its own defense forces that "will be ready to fulfill any orders from the Supreme Commander of the Armed Forces of the Russian Federation."

Meanwhile Crimean Parliament speaker Vladimir Konstantinov said that Poroshenko and the Ukrainian authorities are "activating Western technologies with only one goal - to create conflict between the Ukrainian and the Russian peoples" for their own profit.

Ukraine's new President Petro Poroshenko has taken the oath of office in a swearing-in ceremony in Ukrainian Parliament in Kyiv June 7.

During the speech, Poroshenko announced “Crimea is, was and always will be Ukrainian soil”. The statement was greeted with long applause.

To recall, Crimea was annexed by Russia in March 2014, following the Crimean referendum on the region's status.
