Another 200 Kenyan police officers arrived in Haiti on Tuesday under a U.N.-backed mission to try to quell rampant gang violence in the troubled Caribbean nation, where they were welcomed by senior Haitian and Kenyan police officials.

Haitian sources say the new batch brings the total to 400 Kenyan boots on the ground in violence-ravaged Port-au-Prince, part of a closely watched offer to send some 1,000 police officers to help stabilize the country.

The Kenyan contingent of what is shaping up to be a multinational mission has run into persistent legal challenges in Nairobi, where embattled President William Ruto is simultaneously trying to calm roiling anti-government protests at home.
