Doctor beheaded and two others killed in Nigeria

The men were murdered in front of their wives in the compound the three couples shared in the town of Potiskum, 300 miles northeast of Abuja, the capital.
The state police commissioner confirmed the killing but refused to speculate on whether they were linked to Boko Haram, the al-Qaeda-allied sect that is terrorising northern Nigeria in a bid to rule it under strict Islamic law.
