A senior Baath party organiser and Saddam Hussein aide, Mohammed Younis al-Ahmed, has been named by western intelligence officials as one of the key figures directing the Sunni insurgency from Sources have told The Observer that Younis al-Ahmed - who has had a $1 million price tag placed on his head by the US - is one of between 20 and 50 senior Baath party figures based in Syria who, they believe, are involved in organising the guerrilla war against the US-led multi-national forces in Iraq and against the new Iraqi security forces. The naming of Ahmed comes amid growing concern that hardline factions in Syria are providing protection for cells still loyal to the old Iraqi regime who were involved in organising the flow of money, people and material for fighters in Baghdad and the Sunni triangle. This is despite Syrian moves to tighten up its border with Iraq after complaints from Washington and London that arms and foreign terrorists were crossing into Iraq. The intelligence officials believe the activities of the Syrian-based former regime members - who quickly formed into cells after the fall of Saddam - may be a considerably more significant threat to the interim government of Ayad Allawi than the more widely visible activities of Abu Musab al-Zarqawi, who has been behind a series of beheadings and suicide bombings.
