DUBAI, Jan 31 (Reuters) - Several policemen were injured when a home-made bomb exploded at a roundabout west of the Bahraini capital Manama on Wednesday, the prime minister was quoted as saying.
Sheikh Khalifa bin Salman al-Khalifa said the explosion happened at Budaiya Highway "leaving a number of policemen injured whilst on duty", the official Bahrain News Agency reported late on Wednesday.
A Ministry of Interior message on Twitter put the number of wounded at three and described the device as remotely-detonated and home-made. Both the ministry and Sheikh Khalifa described the explosion as a "terror" incident.
Bahraini police say they have been the target of numerous attacks with homemade bombs since April 2012, including one that killed a policeman in October.
The Sunni Muslim-dominated government has been struggling since early last year to end pro-democracy unrest led mainly by the Gulf Arab kingdom's majority Shi'ite Muslims.
Five home-made bombs killed two people in Bahrain on Nov. 5, and the U.S.-aligned government said the attacks bore the hallmarks of Hezbollah, the Lebanese militant group allied with Iran.
Iran dismisses Bahraini accusations of involvement in the political unrest. Hezbollah also denies involvement, but has criticised the government's handling of protests.
Sheikh Khalifa said that Bahrain would remain stable and its citizens "would foil any terror plot targeting Bahrain to subvert its security," BNA reported. (Reporting By Raissa Kasolowsky and Amena Bakr; Editing by)
