Demonstration in Tehran over Bahrain-Saudi Union

Thousands of people demonstrated in Tehran on Friday to protest a proposed union of Saudi Arabia and Bahrain, in the first step toward closer links among six Arab monarchies across the Gulf.

The authorities had urged citizens to protest what was called an "American plan to annex Bahrain to Saudi Arabia and express their anger against the lackey regimes of al-Khalifa and Al-Saud," the dynasties ruling the two countries.

Media reports said demonstrators in the capital, many brandishing the Bahraini flag, shouted "death" to America, Israel, the "traitors" al-Saud and al-Khalifa.

Official media also reported protests in other cities.

The planned union between Bahrain and Saudi Arabia has triggered a war of words between Shiite-dominated Iran and the Sunni rulers of Shiite-majority Bahrain.

This week’s Tehran Friday prayer leader Ayatollah Kazem Sedighi said the "U.S.-Zionist plot" to create a union between will fail.

"Recently ... (Riyadh and Manama) came up with this plot to annex Bahrain to Saudi Arabia ... They call it a union but they want Bahrain to lose its identity instead of giving in to its people's demands," the cleric said on state radio.

"This is U.S.-Zionist conspiracy and they should know that the Muslim people of the world and the Iranians will not tolerate this plot ... Saudi Arabia did not prevail by its military presence there, and will gain nothing in this plot except disgrace," he added.

Tensions have escalated between Iran and its Gulf Arab neighbors since a Saudi-led Gulf force rolled into Bahrain in March 2011 to boost the kingdom's security forces, which then crushed a month-old Shiite-led uprising against the regime.

Iran has repeatedly voiced support for the protests in Bahrain and strongly condemned the deployment of Saudi-led forces.
