The street lamps on the Kasr El Nil bridge are out. The Semiramis hotel is battered and shuttered: during the latest round of clashes the hotel was looted by a well-armed mob that showed up one night at 2 a.m. The staff called the army and the police, in vain. As our taxi turns the corner by the Semiramis – on the edge of Tahrir Square, a few minutes from the American Embassy – there’s a crowd of young men in the street in front of us. A boy with a keffiyeh wrapped around his mouth winds up his arm and lets loose, aiming squarely at our windscreen – but his hand is empty, he’s just joking. Another boy waves us through. The first boy comes running over and, hanging on the open window, yells at the driver. I’m too flustered to catch what he says, but it’s clear we won’t be let through. We head back to the bridge, back across the Nile, up the other side and home by a different bridge.
