How will world react to Syria chemical weapons claims?
The UN Security Council is holding an emergency meeting over reports of hundreds of chemical weapons deaths in Syria.
Oppositions activists say that rockets with toxic agents were launched at the suburbs of the Ghouta region early on Wednesday morning.
The Syrian army says the accusations have been fabricated to cover up rebel losses.
The BBC's Nick Bryant at the UN and Jeremy Bowen in Cairo examine the international community's reaction to the claims.
