DUBAI, United Arab Emirates: A municipal building was set ablaze overnight in Sunni-ruled Bahrain, the government said Monday, as fresh violence erupted over the executions of three Shiites convicted of a deadly bomb attack on police.

The fire in the building at Shamalia, in the Shiite area of Aali south of the capital Manama, was eventually brought under control, said the interior ministry, without explicitly linking it to the executions.

"According to initial reports, the fire was intentional and the specialized services are taking the necessary measures," the ministry wrote on Twitter.

The blaze came after three Shiites were put to death by firing squad Sunday over the bomb attack on police in 2014, sparking clashes between angry protesters and security forces.

The confrontations continued overnight, with dozens of men and women marching through the streets of Sanabes village chanting slogans against the Al-Khalifa dynasty, according to witnesses.

Demonstrators tried to reach the main street of Sanabes, the hometown of the three executed men.

Sanabes is the closest Shiite village to the Pearl roundabout which was the epicenter of a month-long Shiite-led uprising that the security forces crushed in mid-March 2011.

The square's famous monument was razed to the ground after the protesters were driven out.

Protests turned violent overnight in several other Shiite villages, according to other witnesses who said police opened fire to disperse demonstrators, wounding several of them.

Bahrain's authorities do not permit international news agencies to cover events independently.

The executions were criticized by international human rights groups, as well as Britain and the European Union.

Iran and the Lebanese Shiite movement Hezbollah strongly condemned the executions.

Bahrain, which has been ruled by the Al-Khalifas for more than two centuries, has a majority Shiite population which has long complained of marginalization.

It has been rocked by sporadic unrest since the Gulf-backed security forces brutally crushed the Arab Spring-inspired uprising in 2011.
