British, Italian hostages killed in Nigeria raid
British Prime Minister David Cameron called Italian Prime Minister Mario Monti to inform him of the "tragic conclusion" of the operation, a statement said.
The joint forces intervened to free Italian Franco Lamolinara and Briton Christopher McManus because they were fearful that their lives were under threat, the statement said.
