UN Secretary-General, Mr Ban Ki-Moon, has strongly condemned the brutal killing of students at the Federal Government College, Buni-Yadi, in Yobe.
The condemnation is contained in a statement issued on Wednesday in New York.
It expressed sincere condolences to the bereaved families and hoped that the perpetrators would be swiftly brought to justice.
The secretary-general is deeply concerned about the increasing frequency and brutality of attacks against educational institutions in the north of the country.
He reiterates that no objective can justify such violence, the statement said.
Gunmen suspected to be members of the Boko Haram sect had attacked and killed some students of the Federal Government College Buni-Yadi in Yobe State north-east Nigeria in the early hours of Monday.
Witnesses said the students were attacked in their hostels at night and slain by the hoodlums instead of the usual gun to avoid the attention of security men within town.
The Federal Government College Buni Yadi is a co-educational institution located some 55 kilometres south of Damaturu the Yobe State capital.
Yobe is one of three north eastern states along with Borno and Adamawa put under emergency rule last May by President Jonathan as the military continues to combat the insurgency in the area.
The attack is the fourth recorded on schools in Yobe since the commencement of the insurgency as GSS Damaturu, GSS Mamudo and College of Agriculture, Gujba were attacked last year
