Marches in Kenya to mark a year since massive anti-government demos turned violent on Wednesday, with two killed and hundreds injured as protesters held running battles with police, who flooded Nairobi's streets with tear gas and sealed off government buildings with barbed wire

At least 60 people were killed last year by security forces in weeks of protests over tax rises and the dire economic situation for young Kenyans, peaking when a huge crowd stormed parliament on June 25

Thousands gathered in central Nairobi and other towns on Wednesday, including the families of last year's victims, for initially peaceful anniversary marches

They soon descended into chaos as scattered groups ripped up flagstones to throw projectiles at security forces and chanted for the resignation of President William Ruto

Two people were shot and killed in the town of Matuu, around 100 kilometres (65 miles) from the capital, a hospital official said, with local media reporting that police had fired on protesters
