Police make Syria appeal to UK Muslim women

British counter-terrorism police chiefs have made an unprecedented appeal to Muslim women to urge men against travelling to possibly fight in Syria.
The campaign follows a string of deaths of men from the UK who were fighting against President Assad's regime.
It comes as the UN Secretary General accused all parties in Syria's civil war of "flagrant violations" of international law over the delivery of aid.
