Whether or not the suicide bomber who killed at least 10 people this past weekend in Somalia is from Minnesota, he left a farewell message sure to chill American listeners.
Speaking in English in a taped message broadcast over the Internet, the voice urged other young Muslims to "do jihad in America, do jihad in Canada, do jihad in England, anywhere in Europe, in Asia, in Africa, in China, in Australia.
"Anywhere you find [unbelievers]," the voice continued, "fight them and be firm against them."
On Monday, the bomber's identity remained a mystery, despite reports from some in Minnesota's Somali community who say they recognize the voice as that of a Minneapolis college student who left in November 2008 to fight in Somalia.
Others who know that man well -- Abdisalan Hussein Ali -- and listened to the recording insist that it is not him.
FBI officials said Monday they are conducting a DNA analysis of the bomber's remains to determine his identity.
"We're obviously aware of the incident, and right now the FBI is in the process of doing a DNA analysis," said Kyle Loven, the FBI's chief division counsel in Minneapolis. Results are expected within weeks, Loven said.
Some observers say the message -- posted online by the terrorist group Al-Shabab after a multi-pronged bombing attack Saturday at an African Union base in the Somali capital, Mogadishu -- marks the first time the group has issued a call to launch attacks in the West.
