Hamas has been able to avoid taking sides so far in the mounting tension between Saudi Arabia and Iran, but the higher the pressure rises, the more likely the movement will be forced to choose.
On Jan. 3, Saudi Arabia severed diplomatic ties with Iran after Iranian demonstrators attacked the Saudi Embassy in Tehran, protesting the Saudi execution of Shiite cleric Nimr al-Nimr. Some countries in the region, including Turkey, Iraq, Jordan, Qatar, Morocco and Egypt, sided with Iran in the dispute, while others sided with Saudi Arabia.
