DHAKA: Petro Poroshenko has been sworn in as president of Ukraine, amid hopes the move can help put an end to deadly fighting in the east of the country.

The 48-year-old tycoon has been buoyed by messages of support from the West, after his victory in the 25 May poll.

In his speech Poroshenko called for peace, security and unity, saying he did not want war or revenge, reports the BBC.

Kiev accuses Moscow of backing separatists in the east - a claim denied by the Kremlin.

Poroshenko is being inaugurated in the presence of dozens of foreign dignitaries - including US Vice-President Joe Biden - in the parliament in the capital Kiev.

Former acting president Oleksandr Turchynov began proceedings with a speech welcoming the dignitaries. He thanked Biden for US support for his country.
