Bahraini authorities say a police officer wounded by a bombing on the third anniversary of the start of the Gulf island kingdom's anti-government uprising has died.

The Interior Ministry said Saturday that the officer was one of two injured in what it called a "terrorist blast" the day before in the village of Dair, near the country's main airport. It did not identify the officer.

The ministry also said it arrested 26 people suspected of rioting and vandalism Friday, the anniversary of widespread protests that began in 2011 and set off three years of ongoing unrest in the country. Activists say dozens of protesters have been wounded in recent clashes with police.

Opposition groups dominated by the country's majority Shiites are seeking political rights from the country's Sunni rulers.
