WASHINGTON: United States Secretary of State Rex Wayne Tillerson said religious freedom is "under attack" in Pakistan , citing the marginalization of Ahmadiyya Muslims, a minority sect which Pakistan considers non-Muslim, during the presentation of the annual report on religious freedom required by a 1998 act of congress.

Pakistan Foreign Ministry is yet to comment.

US allies including Saudi Arabia and Bahrain did not uphold principles of religious freedom in 2016, while Islamic State has carried out "genocide" against religious minorities, Secretary of State Rex Tillerson said on Tuesday.

Tillerson made the comments at the State Department while introducing the agency's annual report on religious freedom , required by a 1998 act of Congress. The report is the first to be released during the Trump administration and covers 2016.

Saudi Arabia, Tillerson said, ought to "embrace greater degrees of religious freedom for all of its citizens." He cited criminal penalties for apostasy, atheism, blasphemy, and insulting the Saudi state's interpretation of Islam, as well as attacks and discrimination targeting Shi'ite Muslims.

The kingdom follows the strict Sunni Muslim Wahhabi school of Islam.

The report said Saudi Arabia has used counter-terrorism laws to target atheists and Shi'ite Muslims. The United States and Saudi Arabia have long been close partners in counter-terrorism efforts and the kingdom was the first stop on U.S. President Donald Trump's maiden international visit.

Tillerson singled out another Gulf Arab state, Bahrain, saying it "must stop discriminating against the Shia communities."

Bahrain's foreign ministry said Tillerson's remarks were "inappropriate" and showed "a deep misunderstanding of the facts." It called on the State Department to discuss such matters directly with the kingdom before making statements.

"The history of the Kingdom of Bahrain is characterized by coexistence and religious harmony," the ministry said in a statement. It said Bahrainis of different sects, including Shi'ites, served as government officials, judges, diplomats and other professions.

Tillerson said that in Turkey, a NATO ally, "authorities continued to limit the human rights of members of some religious minority groups." American pastor Andrew Brunson has been jailed in Turkey since October on charges of being part of a terrorist organization, according to news reports.

Tillerson said Islamic State, the Sunni extremist group that has controlled parts of Iraq and Syria, "is clearly responsible for genocide against Yezidis, Christians, and Shia Muslims in areas it controls or has controlled."

Tillerson said Iran targeted religious minorities including Baha'is and Christians, and in 2016 executed 20 people on charges including "waging war against God." He also called out China and Sudan in his remarks.

The Chinese government tortures and imprisons thousands for practicing their religious beliefs, Tillerson said, citing the targeting of Falun Gong members, Uighur Muslims and Tibetan Buddhists. And in Sudan, the government arrests and intimidates clergy and blocks the construction of churches while tearing down existing ones, he said.

Tillerson's decision to introduce the report contrasted with how he handled the State Department's annual human rights report in March. He declined to unveil it in person, breaking with precedent, and drew criticism he was not giving rights issues adequate attention.

The report did not address Trump's attempt this year to temporarily suspend refugee admissions and his decision to impose a lower cap on the number of those admissions. The report states that resettlement is a "vital tool for providing refugees protection."

Many refugees admitted to the United States in 2016 were fleeing religious intolerance and persecution, it said.
