The United Nations has condemned spate of attacks targeting civilians, insisting civilians continue to bear the brunt of conflicts.
"We are particularly reminded of this by the series of terrorist attacks in Konduga, Borno State, on Tuesday
evening that killed 27 innocent civilians and wounded over 80 more," said Edward Kallon, the UN humanitarian coordinator in Nigeria, in a statement marking World Humanitarian Day.
"I condemn this attack and extend my deepest sympathies to the victims and their families."
The UN is concerned about grave human rights violations and sexual and gender-based violence against civilian populations in the north east.
More than 20,000 people have been killed since the start of the conflict in 2009.
Thousands of women and girls have been abducted, and children continue to be used as suicide bombers.
Thousands of families have been forced to flee their villages, rather than build their homes, livelihoods and communities, said Kallon.
"At the same time, health and aid workers, who care for people affected by violence, are affected by the lack of security, which constrains our access to desperately vulnerable communities. People must be put first," he said.
