Saudi Arabia has threatened to recall its diplomats from Iran unless the Islamic republic “improves their protection”

Saudi Arabia has threatened to recall its diplomats from Iran unless the Islamic republic “improves their protection”, the kingdom's deputy foreign minister told reporters 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 Mohammed told reporters.

Iranian students demonstrated on Monday outside the Saudi embassy in Tehran to condemn Riyadh's military intervention in Bahrain and the "murder" of Bahraini citizens, the official IRNA news agency had reported.

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