Barack Obama released a Christmas message expressing solidarity with believers who're targeted for their faith in Jesus Christ.
Mr Obama said he was fortunate that he and other Americans could celebrate the birth of Jesus in peace, and said he was aware many other Christians were unable to exercise their human right to worship God freely.
The US leader also said he was praying for everyone fighting Islamic State, a principal source of persecution against Christians in the Middle East.
He said: "During this season of Advent, Christians in the United States and around the world are preparing to celebrate the birth of Jesus Christ.
"Michelle and I are also ever-mindful that many of our fellow Christians do not enjoy that right, and hold especially close to our hearts and minds those who have been driven from their ancient homelands by unspeakable violence and persecution.
"We join with people around the world in praying for God's protection for persecuted Christians and those of other faiths, as well as for those brave men and women engaged in our military, diplomatic, and humanitarian efforts to alleviate their suffering and restore stability, security, and hope to their nations."
