Bahrain's interior ministry said on Saturday it had arrested 41 people it said were linked to Iran's Revolutionary Guards (IRGC), the state news agency reported.
The ministry said security authorities uncovered a group linked to Iran's IRGC, adding that investigations by the public prosecutor had also involved cases related to sympathy with Iranian attacks.
Iran fired at targets in Bahrain and other Gulf Arab states after the US and Israel launched a war against Iran on February 28.
