Twinkling lights, stars, bells and revolutionary flags are strung above the ancient streets of the old city of Damascus.

Protests have broken out in Syria over the burning of a Christmas tree, prompting calls for the new Islamist authorities to take steps to protect minorities. A video posted on social media showed the tree on fire in the main square of Suqaylabiyah, a Christian-majority town in central Syria.

Syrian Christians attended Christmas Eve services on Tuesday for the first time since the overthrow of President Bashar al-Assad in early December, in an early test of the new Islamist rulers' pledges to protect the rights of the country's religious minorities.
