Bahrain's public security chief, Major-General Tariq Al Hassan, has said that several suspects in Tuesday's bomb blast in Sitra have been arrested.
The Bahraini News Agency reported the arrests on Wednesday in connection with the attack that killed two policemen and wounded six others, quoting Al Hassan.
"Such terrorist acts will not stop policemen from carrying out their duties and taking all security and legal procedures against anyone who puts the lives of citizens and residents at risk or attacks public or private property," BNA quoted him as saying.
BNA reported that various security and legal measures were taken following the incident, including a security deployment and the activation of security points to determine the movement of people in certain areas to ensure the safety of the public and the forces.
On Tuesday Bahrain said the explosives used in the attack resembled some seized at the weekend that the government say were smuggled in from Iran.
The Sunni monarchy often accuses Iran of stirring up unrest among the kingdom's Shi'ite majority. Iran denies interfering in Bahrain but openly supports opposition groups seeking greater rights for its Shi'ite community.
The blast happened south of the capital Manama in the mainly Shi'ite village of Sitra - a hot spot of unrest.
Bahrain was hit in 2011 by demonstrations demanding greater democracy and more rights for Shi'ites, many of whom say they are subject to political and economic discrimination.For all the latest business news from the UAE and Gulf countries, follow us on Twitter and Linkedin, like us on Facebook and subscribe to our YouTube page, which is updated daily.
