Bahrain Mirror- AFP: A bomb exploded on a main street near the Bahraini capital Sunday, causing no casualties in what the government described as a "terrorist" act.

"Terrorist bombing on Budaya Street damages multiple cars without casualties," read a tweet by the interior ministry.

No further details were available.

Bahrain has been rocked by unrest since Shiite-led protests in 2011 were put down by authorities in the Sunni-ruled Gulf state.

The country, ruled by the Al-Khalifa dynasty for more than two centuries, has a majority Shiite population which has long complained of marginalisation.

Bahrain last month executed three men found guilty of killing policemen, including an Emirati officer who was part of a Gulf force that entered the kingdom to help quell protests.

A policeman was also shot dead in a Shiite village last month. Authorities described the shooting as "terrorist."
