Water security in Africa 'unacceptably low', UN warns

In tonight's edition: Heads of states, scientists and campaigners head to Dakar for the World Water Forum as the UN warns that water security across the continent is dangerously low. Also, high seas protection talks fail to reach a deal. The failure comes at the expense of poorer nations and has huge environmental and economic costs. And finally, Burundi bans rickshaws, motorcycle taxis and bicycle cabs for security reasons but drivers say the new rule will put thousands out of work.
