Hundreds of protesters hurled rocks at police on Wednesday in Nairobi as the opposition began three days of demonstrations against rising living costs and tax hikes.

At least 12 protesters were wounded in clashes with police, according to the Associated Press.

According to the Interior Ministry, more than 300 people were arrested during protests and that they will be charged with crimes including looting, destroying property and assaulting police.

Protesters burned tires in the Kibera neighborhood, often a critical location for stand-offs with security forces.

There have been reports of police firing teargas canisters at protesters around Nairobi. 

Demonstrations were reported in several other parts of the country, including the western counties of Kisumu, Migori and Kisii, where the opposition enjoys heavy support. 

Police have arrested suspected protesters in Homa Bay in the country's west, the Nation newspaper reported.

National security agencies have deployed all available resources to maintain order, Interior Minister Kithure Kindiki said on Tuesday.

"Anyone planning to unleash violence on Kenyans is hereby warned to cease and desist," he said.

Nevertheless, the opposition has said protests would continue Thursday.

During earlier protests, police used live rounds and tear gas to disperse protesters, drawing criticism from civil society groups for what they call excessive use of force.

At least 15 people were killed and hundreds arrested in the first two rounds of protests.

​Why are Kenyans protesting?

Schools and shops were closed in the capital and other cities as opposition leader Raila Odinga vowed three straight days of protests against President William Ruto.

"We call on Kenyans to put on their old armor of courage and work to take their country before this dictatorship takes firm roots," the Azimio opposition alliance said.

These latest anti-government protests in Kenya are happening despite the government warning it would not tolerate further unrest after earlier demonstrations turned violent.

This is the third time the opposition staged mass rallies against the government this month, accusing it as illegitimate and responsible for the cost-of-living crisis.

Ruto, who was elected last August in part by pledging to help the poor, announced tax hikes last month. The price of basic commodities has also risen under his administration.

The government defended the move by saying that hikes are needed to deal with growing debt repayments and to fund job-creation initiatives.
