Punch Newspapers Sections Published 5:30 am A former Speaker of the House of Representatives, Mr Yakubu Dogara, has said with the intractable security challenge in Nigeria, some parts of the country are fast becoming a hotbed of instability. The federal lawmaker stated that Nigeria was at war with itself and that for the country, which had reached an inflicting point, to be brought back from the precipice, Nigerians must change the way they think and act. Speaking at the 10th convocation of Achievers University, Owo, Ondo State, on Saturday, Dogara explained that the present challenges confronting the country had long been foretold, but that the warnings were flagrantly ignored, hence the current doldrums the country had been plunged into.
