Heavy clashes continue in the Syrian capital, as activists claim rebels have shot down an army helicopter over Damascus. The footage allegedly shows a military helicopter engulfed in flames shortly before hitting the ground. Activists have accused Syrian security forces of killing more than 300 people in the town of Daraya, near the capital. The government says it carried out an anti-terror operation in the area. Britain responded to the alleged massacre, arguing that it highlighted the urgent need for international action against Assad. While, the Syrian president has vowed to stand firm in the face of what he describes to be a foreign plot against his nation. For more on this, RT talks to UK journalist Neil Clark.
