He survived the attack but his left leg had to be amputated."For some time, journalists have become people to kill in the city," said Sibomana. "We believe that a front has been opened against journalists."Around 10 journalists have been killed in the Democratic Republic of Congo over the last 16 years, with most having worked in North and South Kivu provinces, according to local NGO Journalist In Danger.Both local and foreign armed groups have terrorised residents in the two provinces for some two decades.
