MINNEAPOLIS: One young man attended secret meetings in Minneapolis. Another got a phone call, urging him to leave Minnesota and go to Somalia to fight. Terrorist training videos featuring English speakers pepper YouTube, calling others to the cause.

Details are emerging about how terrorists in Somalia have lured young American men - including as many as 20 from Minnesota - back to their homeland to join their jihad. At least three have died, including one who authorities believe is the first American suicide bomber. Three others have pleaded guilty in the US to terror-related charges.

Court proceedings and interviews with community members, attorneys and terror experts indicate the Somali-based terror group, al-Shabab, uses widespread recruitment tactics including a vast Web-based network.
