The US has said it underestimated the extent to which Islamic State militants had taken hold in Syria.
US president Barack Obama said US intelligence agents had underestimated what was happening in Syria and said Islamic militants had taken advantage of the Syrian civil war to “reconstitute” themselves.
US-led forces have been bombing ISIl targets in Syria for the last week .
Obama justified his country’s intervention in Syria in an interview with CBS television saying “America leads. We have capacity no one else has. Our military is the best in the history of the world”
He also acknowledged the contradiction in opposing Syrian President Bashar al-Assad while at the same time battling Islamic State militants who Assad is fighting.
Overnight on Sunday, some of the strikes hit mills and grain storage areas and killed civillians – possibly mistaking them for an ISIL base – according to the Syrian Observatory for Human Rights, based in Britain.
Meanwhile Islamic State militants are getting closer to the Syrian town of Kobane on the border with Turkey.
Many Turkish Kurds are angry that the Turkish government is preventing them from crossing the border to fight ISIL in Syria.
