PORTLAND, Maine (NEWS CENTER) - It was a deadly attack at a mall in Nairobi, Kenya that left 68 people dead.

Then came an unconfirmed twitter feed from the group Al Shabab claiming responsibility for the attack. In it a claim that one of the attackers is from Maine. A leading American expert on terrorism says Al-Shabab has attempted to recruit people in several American cities including Portland, Maine.

"It's a very specific short list of places San Diego Minneapolis Seattle, Washington and Portland, Maine", said terrorism expert Evan Kohlmann.

There are about 6,000 members of Portland's Somali community.

"The fact that I can't say they cannot be recruited I'd be lying if I told you that but we've never seen a single case in Maine", Dini said.

Dini says members of his community came here to escape the violence back home, not become a part of it.

Portland and Maine State Police say they have been in contact with the FBI, which is the agency taking the lead on following up on these reports.
