Sarway also reported that an Afghan security official said they were fighting a very organized group of suicide attackers. Steve Herman, a Voice of America reporter, notes on Twitter that the hotel is located at the top of a hill, “with rings of security.” He writes, “Not easy for bad guys to penetrate.”

The hotel, which is no longer associated with the Intercontinental chain, but is still “popular w/ afghan VIP + expat crowd, sprawling ground, hosts dinners/events,” describes Tom Popyk, a reporter for Global TV Canada. Or, to put it another way, Matthieu Aikins a writer for Harper's, writes, “Intercontinental is haunt of expats and Afghan elite.
