Gunmen on Monday attacked a Nigerian police base in the capital, Abuja, where Boko Haram militants are often held. A police statement said the attack was repelled but that 30 detainees escaped, 25 of whom were recaptured. No group has claimed responsibility for the attack. But Ike Abonyi, who is news director of the Nigerian Daily This Day, says he believes Boko Haram is sending a message to the government.
