American forces are "ready" to launch strikes on Syria if President Barack Obama chooses to order an attack, US Defence Secretary Chuck Hagel says.
The crisis follows last Wednesday's suspected chemical attack near the Syrian capital, Damascus, which reportedly killed more than 300 people.
French President Francois Hollande said France was "ready to punish" whoever was behind the attack, and had decided to increase military support for Syria's main opposition.
