The police fired tear gas and shots rang out on Tuesday as thousands of demonstrators flooded the streets around Kenya’s parliament in the capital, Nairobi, after lawmakers passed tax increases that critics say will make life onerous for millions.

At least five people have died from gunshot wounds and more than 30 others were wounded in clashes between protesters and the police, according to a joint statement by Amnesty International and several prominent Kenyan civic organizations. That could not be independently confirmed. A video posted to social media by the independent Kenya Human Rights Commission showed the police firing as protesters marched towards them.

The parliament building was breached and its main entrance was briefly on fire, and Kenya’s Red Cross said that its vehicles had been attacked and staff members injured.

The turmoil over the finance bill that includes the tax hikes has shaken Kenya, an East African economic powerhouse of 54 million people that has long been an anchor of stability in a tumultuous region. At least one person was killed and 200 others were injured in protests across the country last week, according to Amnesty.
