FBI arrests 18-year-old ISIS supporter in plot against Mall of America

The FBI arrested Sheikhdoon Abdullahi Mohamud, an 18-year-old American citizen, for allegedly planning an attack on an arts festival at the Mall of America in Bloomington, MN. This is the seventh ISIS-linked terrorism case in the US this year, indicating a persistent domestic threat. The arrest disrupts a specific plot, but the broader trend of ISIS-inspired attacks continues.
