NAIROBI – The death toll from Monday’s anti-government protests in Kenya has climbed to 31, representing the highest number of casualties in a single day since the protests began earlier this year, announced the state-backed human rights commission on Tuesday.

According to the commission, an additional 107 individuals were injured, and more than 500 were taken into custody as extensive property damage occurred, including damages to supermarkets. The number of arrests was similar to that reported by the police. The death toll did not specify whether security personnel were among the deceased.

For several weeks, young people and other citizens have rallied in the streets against police violence, poor governance, and demanding President William Ruto step down due to alleged corruption and the increasing cost of living.

Ruto has not commented on Monday’s protest or its toll.

The U.N. high commissioner for human rights, Volker Türk, on Tuesday urged that the grievances leading to the protests are addressed. Spokesperson Ravina Shamdasani said he “renews his call for calm and restraint, and full respect for the freedoms of expression, association and peaceful assembly.”

Monday’s demonstrations, which were met with police roadblocks preventing access to downtown Nairobi, were planned to coincide with the 35th anniversary of the historic Saba Saba pro-democracy protests. Saba Saba is Swahili for Seven Seven.

July 7 holds deep significance in Kenya, marking the first major pro-democracy protests in 1990 that called on then-President Daniel arap Moi — Ruto’s political mentor — to transition from a one-party state to a multiparty democracy. That demand was realized during the 1992 general elections.

This year’s wave of protests was sparked by a blogger’s death in police custody last month. Police shot a civilian at close range during a protest on June 17. On June 25, thousands of youths turned out across the country.

A total of 50 people have been killed in the protests over the last two weeks.

The Kenya National Cohesion and Integration Commission, a government body whose commissioners are appointed by the president, on Tuesday urged politicians not to fuel ethnic tensions and criticized police for using excessive force towards protesters.

Interior Minister Kipchumba Murkomen last week told police to “shoot on sight” anyone who approaches police stations during protests after several were burned.

The public anger has built on Ruto’s efforts to make Kenyans pay more to help pay off massive government debt. Last year, thousands of young people protesting rising taxes stormed parliament, leading Ruto to promise to cut government spending.

With some people taking advantage of the chaos, some businesses have said they have lost large amounts of goods.

“They invaded our shop, and by the way, we have lost so many things. We lost cash, phones, a lot of them,” mobile phone seller Nancy Gicharu said.
