5 minute curfew

I was just coming out of the British Embassy this morning after quite a good meeting with DFID, when the guards at the gate told me, "please wait, 5 minute curfew". I must admit to wondering what was going on. In fact the road in front of the embassy had been cleared so that VIPs and their security could drive straight through without stopping. It seemed to be that an awful lot of cars went by, so I don't know if it was just 1 VIP or a number. The guards at the gate were joking around as to who it might have been, but I don't think anyone really knew. After about 10 mins, the traffic got back to normal (chaotic) and I was allowed out to get to my driver and my car!!
