Claims that strikes would violate sovereignty, as Syrian rebels welcome move and other Arab states offer 'appropriate' support
A tale of two speeches: emboldened Obama moves from dove to hawk
Illegal? Irrational? Irrelevant? Obama's Isis address falls down on every front
The Syrian government and its close allies in Moscow and Tehran warned Barack Obama that an offensive againstIslamic State (Isis)withinSyriawould violate international law yesterday, hours after the US president announced thathe was authorising an open-ended campaign of air strikes against militants on both sides of the border with Iraq.
Syrian opposition groups welcomed Obama's announcement and called for heavy weapons to fight the "terror" of Isis andBashar al-Assad. Saudi Arabia and nine other Arab states pledged to back the US plan "as appropriate".
Hadi al-Bahra, head of the western-backed Syrian National Coalition, said the group "stands ready and willing to partner with the international community not only to defeat Isis but also rid the Syrian people of the tyranny of the Assad regime". In Reyhanli, on the Turkish-Syrian border, a spokesman for the Free Syrian Army (FSA) said that moderate anti-Assad forces urgently needed anti-tank and anti-aircraft missiles.
