Abuja - UN Secretary-General 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.
On Tuesday, President Goodluck Jonathan condemned the killings, calling them "heinous, brutal and mindless".
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.
