Prime Minister David Cameron said on Tuesday Britain would support Nigeria in reforming its anti-terrorism security after a string of deadly bombings in Africa's most populous nation, Reuters reported. Most of the attacks have been around Maiduguri, a city in one of the poorest regions in Nigeria, close to borders with Cameroon, Niger and Chad. More than 150 people have been killed this year in the city of about 1.2 million people. A Cabinet Office Briefing Room (COBR) is the formation of a crisis response committee in Britain, coordinating the actions of security bodies within the government. -- SPA
