Riyadh: Saudi Arabia has threatened to recall its diplomats from Iran unless the Islamic republic improves their protection, the kingdom’s deputy foreign minister said on Sunday.

“I hope we won’t be obliged to withdraw our diplomatic mission from Tehran if Iran fails to take the necessary measures to protect it,” Prince Turki Bin Mohammad told reporters.

Last Monday Iranian students demonstrated outside the Saudi embassy in Tehran to condemn Riyadh’s military intervention in Bahrain, the official Irna news agency had reported.

Iran’s Fars news agency had reported that “six to seven petrol bombs were hurled against the embassy” as students chanted slogans against the authorities in Saudi Arabia and Bahrain.

On Sunday, Prince Turki said: “Shiites in the Gulf are our brothers and have national rights under the umbrella of their loyalty (to their countries) and not to the outside.”

Iran has repeatedly condemned the dispatch of Saudi troops to Bahrain to support the Bahraini crackdown on demonstrations there.
