US says Syria's UN move too late
Inspectors granted access to gas-attack site as Iran, Russia warn against military intervention

Syria agreed to allow the United Nations to inspect the site of a suspected chemical weapons attack from today but a US official said it was already too late.
This comes as Syria warned that any US military action would "create a ball of fire" in the Middle East and Iran warned Washington against any intervention.
The UN said Damascus had agreed to a ceasefire while a UN team of experts are at the site for inspections. But there were increasing signs that the US and its allies were considering taking action, a year after President Barack Obama said the use of chemical weapons was a "red line" that would incur serious consequences.
Speaking after Syria's decision to allow the UN team to the site, a senior US official said there was very little doubt that the Syrian government had used a chemical weapon against civilians last Wednesday and that Washington was still weighing how to respond.
