State Department deputy spokeswoman Marie Harf said Monday that there's no chance he could end up at Guantanamo.
"The administration's position on Guantanamo is clear. Our goal is not to add to the population, it's to reduce it, which we've done. ... Our policy is not to send any new detainees to Guantanamo," she said.
Concern grows over terrorism in region
The weekend attacks come as concern over terrorism in the region is on the rise after last month's deadly shopping mall attack in Kenya's capital.
Al-Shabaab claimed responsibility for the attack, which left at least 67 people dead.
A U.S. official said Monday that the U.S. government is concerned about the al Qaeda-linked militant group's growing focus on external operations -- including the possibility of striking U.S. interests in the region.
The Somalia operation was planned before the mall attack, the official said.
Another source underlined that the raid was not in response to the mall attack, adding that the United States has been going after Al-Shabaab for some time, with SEALs and with drones.
