Bahrain calls for Iranian diplomats to leave the country within 48 hours.
Bahrain has severed diplomatic relations with Tehran following storming of Saudi diplomatic missions in Iran, state news agency BNA reported.
"Bahrain decided to break off diplomatic relations with the Islamic Republic of Iran and calls upon all members of the mission to leave the kingdom within 48 hours," BNA said.
On Saturday, demonstrators protesting in Iran against the execution of Sheikh al-Nimr by Riyadh attacked the Saudi embassy in capital Tehran and the consulate in the city of Mashhad. The protests continued on Sunday.
Iranian diplomats were ordered to leave the country within 48 hours, while 47 of Saudi diplomatic mission staff have safely returned to their homeland with the help of the United Arab Emirates.
Al-Nimr was among 47 people convicted on terrorism charges whose execution Saudi Arabia announced on Saturday, setting off a diplomatic row and exacerbating sectarian strife.
According to the Al Arabiya news channel, Riyadh announced on Sunday cutting ties with Tehran and decided to evict Iranian diplomatic mission from Saudi Arabia.
