Kenya votes in new constitution referendum
Kenyans are voting in a referendum on a new constitution, the centrepiece of measures designed to reform politics.
It limits the powers of the president and sets up a commission to settle land disputes that fuelled violence in the past. Both the president and the prime minister are backing the "Yes" vote.
The referendum was part of a deal that ended deadly clashes after a disputed election in December 2007 when more than 1,000 people were killed.
