With the standoff apparently drawing to a close after three days, there was a growing focus on the identity of the militants and how they could pull off a sophisticated assault that killed at least 62 people and kept security forces at bay for three days. Kenyan Foreign Minister Amina Mohamed said Monday that “two or three Americans” and “one Brit” were among the perpetrators of the attack. 

She said in an interview with “PBS Newshour” that the Americans were 18 to 19 years old, of Somali or Arab origin and lived “in Minnesota and one other place” in the United States. The British jihadist was a woman who has “done this many times before,” Mohamed said.

U.S. officials said Monday that they were pressing to determine whether any of the assailants were American. 

“But at this point we have no definitive evidence of the nationalities or identities of the perpetrators,” said State Department spokeswoman Jen Psaki.
