US equity futures take a hit- S+P 500 now pricing the opening below 5,600

In the past few minutes all the US equity futures just lurched to the left and have dropped back further into the red. The losses are broad in the sense that all three major indexes are tracking lower at the same time. Stocks here in Europe have fallen back and the earlier rebound from below 22,200 is now seeing the DAX fall back towards that level again. The S+P was pricing the opening well above 5,600 earlier. It s right now close to session lows, pricing it below that level, but of course the price action remains fluid and volatility is showing little signs yet of easing
