The death toll from two overnight attacks in eastern Democratic Republic of Congo shot up to at least 50, monitors said Monday. Citing a toll that is "still provisional", the Kivu Security Tracker (KST) group said 28 people were killed in Boga and 22 in Tchabi, villages lying about 10 kilometres (six miles) apart in area that has long had a reputation for Allied Democratic Forces (ADF) attacks and ethnic friction. The earlier toll was at least 39 dead. bur/mbb/gd/ri
