Syria attack: Make it clear there are 'limits'

The UN Security Council will meet in emergency session today to discuss Tuesday's suspected chemical attack in the province of Idlib, in northwestern Syria.

Dr Anne-Marie Slaughter, the former head of policy at the US State Department under Obama and Clinton, says the international community needs to make it clear there are limits and be prepared to take action against Syria.

She told the Today programme if Donald Trump wants to strengthen his hand at the negotiating table then he needs to make it clear the international community can't be "pushed indefinitely".
