At least 11 people have died and more than 500 were arrested in anti-government protests across Kenya on Monday, according to the country’s National Police Service.

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.

The death toll from Kenya’s latest anti-government protest has surged to 31, according to the state-funded human rights commission.
