At least 26 Kenyans are still missing after being abducted by security forces over the past year, according to rights groups. Their families want answers.

Demonstrators joined antigovernment marches across the country a year after huge rallies against a contentious tax plan left more than 60 people dead.

Several protesters were killed and at least 400 others were wounded on Wednesday when antigovernment protests in the capital, Nairobi turned deadly. Kenyan officials have not disclosed the number of casualties. Reports from media and rights groups varied, placing the number of dead between eight and 16.
