Lagos, Safar 23, 1437, Dec 5, 2015, SPA -- Nigeria's intelligence agency says it has arrested nine alleged Boko Haram extremists plotting attacks on Abuja. Saturday's statement follows a warning Friday from the U.S. Embassy that extremists may be planning attacks on hotels favored by Westerners, AP reported. The Department of State Security says one of the nine men arrested was carrying out surveillance of a "high-profile hotel." It says all nine were detained in the past month and had infiltrated the capital in central Nigeria from the country's northeast where most extremist attacks occur. --SPA 21:31 LOCAL TIME 18:31 GMT www.spa.gov.sa/w
