Authorities arrested “more than 10” suspects, including four at the airport, who are thought linked to the Shabaab assault on a Nairobi mall. The death toll was revised to at least 62; the military said all floors of the mall have been cleared, but there were also reports that some gunmen remained. A Shabaab commander said the assault was well organized. Kenyan authorities believe foreign fighters were part of the assault team. Wanted British terrorist Samantha Lewthwaite is suspected of involvement in the attack.
