Another blast in Sadr city.

Mosul: a slow start, then a 'steady trickle' and now flow appears to be increasing, as reported by Fox News from one polling center in the north of the city. Despite some mortar attacks in Mosul, a Lieutenant Colonel reports that he is very optimistic.

Up1: CNN reports there is 'quite a steady stream' in Kurdish areas of Mosul, but less so in non-Kurd areas of the city, and reports very few voters in Tikrit, Saddam's home town.
