WASHINGTON -- From pork rinds sprinkled on Muslim graves in France to a Christian pastor’s death sentence for apostasy in Iran, religious minorities were targeted across the globe in 2011, according to a U.S. government report Monday on the state of religious freedom.

The State Department’s annual compilation highlighted a few narrow openings in unlikely places – transitional Libya and closed-off Myanmar, for example – but it also criticized some traditional U.S. allies for backsliding when it came to protecting the freedom to worship.

Europe in particular was chided for failing to keep pace with its growing ethnic and religious diversity, with the report saying that the demographic change is sometimes accompanied by “growing xenophobia, anti-Semitism, anti-Muslim sentiment, and intolerance toward people considered ‘the other.’”

Belgium and France passed laws restricting dress that “adversely affected Muslims,” while Hungary introduced changes making it so difficult to register religious organizations that the number of recognized religious groups plummeted from more than 300 to fewer than 32.

"Members of faith communities that have long been under pressure report that the pressure is rising," Secretary of State Hillary Rodham Clinton said in Washington. "Even some countries that are making progress on expanding political freedom are frozen in place when it comes to religious freedom. So when it comes to this human right, this key feature of stable, secure, peaceful societies, the world is sliding backwards."

Religious freedom also was a fraught subject in the so-called Arab Spring rebellions, the waves of popular protests that unseated four Middle Eastern rulers and plunged the region into a complicated transition ostensibly toward more democratic rule. But many of the uprisings and transitions have taken on sectarian undertones, a trend now evident in the 16-month-old Syrian revolt.

In Syria, the report found, the embattled regime of President Bashar Assad “targeted and destroyed churches and mosques across the country” in the early waves of protests. The investigators blamed the regime for propaganda that painted the protesters as “extreme Islamist factions” and also chided the protesters for conflating regime violence with perceived offenses by the Alawite minority, the sect of Assad and his top cronies.

“This led to an increase of tension, violence and killing between largely Alawite and Sunni communities,” the report said. “Some Christians, Druze, and opposition members also suffered at the hands of the regime. As the violence grew, members of minority religious communities were increasingly vulnerable.”

In Bahrain, where neighboring Sunni Muslim bulwark Saudi Arabia sent troops to crush a mainly Shiite rebellion, the government arrested and detained protesters, “the vast majority” of them Shiites. The report also noted the destruction of 53 religious structures, mostly Shiite places of worship, in the unrest.

Meanwhile, revolutionary Egypt has “failed to curb rising violence against Coptic Christians,” the report found, noting that no government officials were held responsible for an attack on protesters by authorities that left at least 25 people dead and more than 300 injured, most of them Copts.
