A village chief believed to have ordered the killing in March of two UN experts in the Democratic Republic of Congo was arrested Saturday, a Congolese military spokesman said. Congolese authorities have from the start said the suspect, Constantin Tshidime Bulabula, was behind the slayings of Swedish-Chilean Zaida Catalan and American Michael Sharp, who were investigating reports of dozens of mass graves in the war-torn Kasai region.

Catalan and Sharp reportedly left the city of Kananga on March 12 and their bodies were found 15 days later. Catalan had been decapitated.
