Civilian pickup trucks loaded with casualties and ambulances with sirens blaring were seen racing from the scene after two suicide bombers, one in an explosives-laden car and the other on foot, hit a funeral procession in Baghdad that killed at least 92 people today.
The explosions set the tents and several nearby cars on fire, sending a towering plume of thick black smoke over the city.
