epa03861941 Opponents of a possible military strike on Syria hold a sign that reads 'No War On Syria', as they gathered outside the White House to listen to US President Barack Obama give a live address to the nation from the East Room of the White House, in Washington DC, USA, 10 September 2013. President Obama discussed solutions to defuse the crisis in Syria, including the Russian proposal to put Syria's chemical weapons under international control and possible military strikes. Obama has met some opposition lobbying Congress to back a limited strike on Syria, after Bashar al-Assad's government allegedly carried out a sarin gas attack on 21 August that killed more than 1,400 people.
