A Christmas tree is set up at the Christian compound next to a mosque in Abu Dhabi, United Arab Emirates, Tuesday, Dec. 15, 2009. The majority of Gulf's two million Christians can only pray in secret. At least 1.4 million Christians work and live in Saudi Arabia. They are mostly migrant workers from the Philippines, India and other Asian countries, as well as Arab expatriates from across the Middle East, who have been attracted by job prospects in the kingdom's oil industry.
