The death of blogger Albert Ojwang in police custody last month has given the protests fresh impetus, fuelling anger against the authorities and bringing hundreds onto the streets.

At least 10 people were shot dead and 29 injured in Kenya as anti-government protests erupted after restarting early last month.

The UN human rights office on Tuesday said it is "deeply troubled" by the recent killings during nationwide protests in Kenya, as well as looting and destruction of property.
