The attack on the Indian Army's Lubero post in the troubled province of North Kivu in Congo was carried out by a Mai Mai group which has recently attacked Congolese Army positions.
A DRC army spokesman, Mak Hazukay, blamed the attack on ADF rebels.
UN Secretary-General Antonio Guterres on Monday strongly condemned a series of attacks attributed to the Allied Democratic Forces rebels in the Democratic Republic of Congo (DRC), which killed two peacekeepers and injured 18 others. "But during the attack, two Indian peacekeepers", Col Anand said.
As per the requirements of UN Mission, India has deployed a total of 2,664 military personnel in the disturbed region of Congo.

"The mission deployed attack helicopters as well as the force intervention brigade in support of operations as well as to reinforce presence", he said, adding that mission forces are also deployed to restore order and protect the population. Officials claim that President Joseph Kabila's refusal to step down at the end of his constitutional mandate last December has fuelled unrest in the country's eastern provinces.
