Foreign fighters have been slipping back into Iraq in larger numbers recently and may have been behind some of the most devastating attacks this year, reviving a threat the US military believed had been mostly eradicated, intelligence officials said.
It is impossible to verify the number of foreign insurgents entering the country. But one Middle Eastern intelligence official estimated recently that 250 came in October.
US officials say the figure is far lower but have acknowledged an increase since August.
At the same time, Iraqi officials said there has been a surge in financial aid to Al Qaeda’s front group in Iraq as the US military prepares to leave by the end of 2011.
They said it reflects fears by Arab states over the growing influence of Iran’s Shi’ite-led government over Iraq and its Shi’ite-dominated government.
It's absolutely amazing how the US keeps getting everything wrong in Iraq.
We'll be leaving behind a proxy war between Iran and al Qaeda.
Whoever wins, we lose.
