Abuja: Nigeria’s government vowed Tuesday to track down gunmen who stormed a luxury hotel and murdered two aid workers, a British woman and a Nigerian man, before abducting three other people. "The security agencies will leave no stone unturned in their efforts to apprehend the killers and bring them to justice,” the minister of information and culture, Alhaji Lai Mohammed, said. Police were doing "everything possible” to secure the safe release of the three kidnap victims, he added. (AFP)
