Syria's 2,000-year-old Christian community is being devastated by the country's civil war.
A Swedish journalist interviewed more than 100 Syrian Christian refugees in Turkey and Lebanon. They say Muslim rebel militia are driving them out because of their faith.
One woman said her husband and son were shot in the head just because they were Christians.
Syria's population of 2 million Christians is the second largest in the Middle East after Egypt, and now whole villages are disappearing when Islamist rebels arrive.
Every week, hundreds of Syrian Christians arrive in Lebanon. A Lebanese patriarch said it is a ''great exodus taking place in silence."

Meanwhile, Secretary of State John Kerry said the Obama administration will give the Syrian opposition an additional $60 million in aid.
Kerry said the United States will also for the first time provide food and medical supplies to the rebels fighting to remove President Bashar Assad.
He announced the new support and change in policy in Rome Thursday, where an international conference on Syria is being held. European nations are expected to follow Kerry's example.
Kerry said the goal of the aid is to put more pressure on Assad to step down and to make way for a democratic transition.
