Attacks on Christians for their faith are escalating around the world.

Here's an article highlighting the attacks on Christians for their faith.  The most violent attacks are obviously in Muslim countries but also many others.

This past month, I spent an afternoon at ACN headquarters in Greenpoint, Brooklyn, with the Maronite ordinary of Syria, Bishop Elias Sleman. He described the Muslim crimes against Christians that have driven members of his flock to mountain hiding places, where they are barely subsisting...

As for 21st century atrocities, we are fortunate to have the newly published, "The Global War on Christians: Dispatches From the Front Lines of Anti-Christian Persecution," by the Catholic reporter, John L. Allen, Jr.

Mr. Allen points out that the word “war” has in recent times been used too freely to promote various causes, i.e., war on women, war on Christmas. In his judgment the correct usage means, “facing [a] situation with the necessary sense of urgency.” And because 80 percent of acts of religious discrimination in the world today are directed at Christians, Allen holds that there is a compelling urgency for talking about a war on Christians....

Since the turn of the century, advocacy groups have estimated that 100,000-150,000 Christians have been martyred annually. Other forms of harassment Christians must endure, particularly in countries where they are a minority population, include societal discrimination, employment discrimination, legal discrimination, as well as suppression of Christian missionary activity and worship, and forced conversions from Christianity.

The Pew Forum on Religion and Public Life reports that between 2006 and 2010 some form of harassments against Christians occurred in 139 nations — approximately three-quarters of the world’s countries. Thirty-seven percent of them have “high” or “very high” restrictions on Christian activities.

This year the Open Doors World Watch listed the “most hazardous nations on earth in which to be a Christian.” The number one nation on the list of 25 was North Korea, followed by Afghanistan, Saudi Arabia, Somalia, and Iran. Eighteen of the countries on the list are majority Muslim.

These are places were Christians are attacked physically, often facing prison or loss of life.  It doesn't touch on the growing attacks on religious freedoms of Christians in the West.
