President Obama takes cautious approach on Syria

President Obama has said he won't be rushed to respond to Syria's apparent use of chemical weapons.

Mr Obama said chemical weapons had been used in Syria, but added, "we don't know how they were used, when they were used, who used them".

The UN says more than 70,000 people have been killed in Syria since the uprising against President Bashar al-Assad erupted in March 2011.
