Ukrainian Prime Minister Mykola Azarov has offered his resignation, according to a statement on the government's website.

Azarov said he was stepping down to try and encourage a "social-political compromise" to the unrest in the country. Ukraine has seen months of protests and violent clashes.

In a statement he said "Today the most important thing is to preserve the unity and integrity of Ukraine. This is far more important than any personal plans or ambitions. That is why I have taken this decision".

The rallies began in November last year after President Viktor Yanukovych scrapped a treaty with the European Union in favour of a bail-out loan from Russia, following lobbying by Russian President Vladimir Putin.

The move comes as an extraordinary parliamentary session gets underway in the capital Kiev, aimed at adopting vital reforms. This includes abolishing anti-protest laws that have stoked tensions with the opposition protesters.

Just minutes after the session started, politicians suspended the session for a pause to agree and agenda for the day. A minute's silence was held for those killed during clashes in Kiev.
