MAIDUGURI:

Nigerian authorities imposed a 24-hour curfew in the main north-eastern city of Maiduguri yesterday after suspected Islamist militants staged an attack there in the early hours. Baba Ahmed Jidda, a spokesman for the government of Borno State, of which Maiduguri is the capital, announced the curfew in a statement, but provided no details about the attack or if there were any casualties.
