Police in Kenya have clashed with demonstrators during anti-government protests that saw authorities block major roads leading into the capital, Nairobi, and most businesses closed.

Kenya's security forces have blocked all major roads leading into central Nairobi, ahead of planned nationwide protests. Much of the city centre is deserted, with businesses shut and a heavy security presence on the streets. Some schools have advised students to stay at home.

At least 10 people died across Kenya and hundreds were arrested during anti-government demonstrations on Monday, a rights group and police said, following clashes between police and protesters in the capital Nairobi's outskirts.
