Labour MPs have called for a Syrian no-fly zone enforced by the British navy, with strikes against planes dropping illegal weapons.
A statement released by the MPs says "for too long, the international community has stood back and done nothing", and that immediate action must now be taken.
"In the short term, an internationally-led no-fly zone should be set up in Idlib province as soon as possible to prevent further civilian deaths," the statement says.
"In addition, whilst DFID’s support for refugees in Lebanon and Jordan is welcome, we, and other European countries, must take our fair share of Syrian refugees too, something this Government has so far failed to do."

- Rachel Reeves MP, LCID Co-President
