Ukraine's president Petro Poroshenko has hailed the signing of an European partnership agreement as the country's most historic day since independence in 1991.

The pact - which binds Ukraine more closely to the West both economically and politically - is at the heart of the crisis in Ukraine.

Mr Poroshenko also explained the significance of the pen which he had used to sign the agreement.
