Queues as Kenyans go to the polls in crucial election

4 March 2013 Last updated at 17:24 GMT

Long queues are reported nationwide as Kenyans vote in an election that observers describe as the most important in the country's history.

Polls were due to close at 17:00 (14:00 GMT) but officials said those in queues at that time would be allowed to vote.

There has been violence around the port town of Mombasa, with at least five police officers killed in one attack.

Early provisional results suggested the two main presidential candidates were far ahead of the rest of the field.
