Bahrain says it has filed a formal protest with Iran over a broadcast translation that wrongly substituted Bahrain for Syria in a speech by Egypt's president.

A statement by Bahrain's government says Egypt's President Mohammed Morsi referred to the Syrian rebels fighting an "oppressive" regime during a speech at a Tehran conference Thursday.

Instead, Bahrain claims Iranian state TV replaced the word "Syria" with "Bahrain" in its Farsi translation.

Morsi's speech was an embarrassment for Iran, which is a close ally of the Syrian regime. But Shiite power Iran has frequently criticized Bahrain's authorities for crackdowns against mostly Shiite protesters seeking greater political rights.

Bahrain says the formal complaint was filed Saturday with an Iranian diplomat.
