The battle for Syria

At least 40 people are dead and another 100 injured after explosions in a border town in southern Turkey, says the interior minister.

A UN investigator says there is evidence rebel groups may have used chemical weapons, as the battle for the Middle East's largest chemical weapons facility continues to rage.

Concerns are raised that the stage is being set for foreign military intervention in Syria following a second Israeli airstrike in Syria in two days.

David Cameron has said 'growing evidence' suggests chemical weapons have been used in Syria, but rebels have been saying this for a year. Channel 4 News looks at the evidence online.

The use of chemical weapons in Syria is a "war crime" David Cameron says, but adds it is "unlikely" British troops will be sent into the war-wracked country.

At least 100 people are reported dead after a major Syrian army offensive in the suburbs south of Damascus, say opposition groups, who are calling the attack a "massacre".

The Syrian government has carried out repeated, indiscriminate and sometimes deliberate, air strikes against civilians, a report from Human Rights Watch says.
