Gunmen kill students at Nigerian college

LAGOS (Reuters) - Gunmen opened fire in a student residence in northeastern Nigeria on Tuesday, killing and wounding an unknown number of people, emergency services and a security source said.

The attack took place at the Federal Polytechnic Mubi in Adamawa state which, like much of the north, has been targeted by Islamist insurgents. But police were also looking at whether the killings might have been part of a political feud inside the college.
