This undated image posted on a militant website purports to show militants in the al-Jazeera region on the Iraqi side of the Syria-Iraq border. Last month, militants inside Iraq killed 48 Syrian government troops who had sought refuge from the war in their country _ an ambush that regional officials now say is evidence of a growing cross-border alliance between two powerful Sunni jihadi groups _ Al-Qaida in Iraq and the Nusra Front in Syria. Middle Eastern intelligence officials said the jihadi groups are sharing military training compounds, logistics, intelligence and weapons as they grow in strength around the Syria-Iraq border, particularly in a sprawling region called al-Jazeera, which they are trying to turn into a border sanctuary they can both exploit.(AP Photo)
