Iran agrees with the US that the use of chemical weapons in Syria is a "red line" that cannot be crossed. But while the US thinks, but can't say for sure, that the government used chemicals on rebel fighters, Iran suggests precisely the opposite, reports Reuters. Its foreign minister today called on the UN to investigate Bashar al-Assad's claims that anti-government fighters used toxins, reports the AP.
"We have always emphasized that the use of chemical weapons on the part of anyone is our red line," said Ali Akbar Salehi. "We have also requested that in accordance with the Syrian government, which emphasizes that the opposition has used these weapons, the United Nations ... identify the main culprit in this regard, which is the opposition." Tehran, like the US, didn't spell out what it would do if it got such evidence, but it presumably means more direct military intervention. (Read more Iran stories.)
