Four Bahraini members of the cell were detained by authorities in neighboring Qatar after they entered the Gulf Arab state from Saudi Arabia, the state news agency BNA quoted an interior ministry spokesman as saying.

The four had documents and a computer that included details on vital installations, the news agency added.

“The Qatari security authorities questioned the suspects and inquiries in Qatar revealed that the suspects had illegally left Bahrain after being incited by others to head to Iran, passing through Qatar and Syria, to establish a group that carries out armed terrorist operations in Bahrain against vital establishments and individuals,” BNA reported.

“Inquiries to date have confirmed that the suspects were targeting the King Fahd Causeway, the Ministry of Interior building, the Saudi Arabian embassy and individuals,” it added.

The agency said the four carried unspecified sums of foreign currency, including US dollars and Iranian rials, and had flights booked to Syria.

BNA said the four suspects gave information about a fifth member of the group in Bahrain, who was also arrested.
