A Bahraini security court has sentenced 14 people to life in prison in the killing of a Pakistani man during unrest related to pro-reform protests earlier this year.

It was one of three lengthy sentences handed down in Bahrain Monday, as the island kingdom deals with participants in the protests that were led by the country's Shi'ite majority.

The official BNA news agency says the Pakistani man was assaulted with wooden planks and metal bars in Manama during the protests. The court sentenced 15 others to 15 years in prison each for the attempted murder of a soldier.

And in a third case, the court sentenced six Bahraini students to 15-year prison terms and a seventh to 18 years in prison on charges of inciting violence and attempting to murder others at their university.

Bahrain has imprisoned hundreds of people since the country's Sunni rulers imposed martial law in March to deal with protests by the Shi'ite majority demanding greater rights.

Last week, a military court sentenced medical personnel to prison terms ranging from five to 15 years.

Bahraini authorities accused the doctors and nurses of using the hospital for anti-government activity, of possessing firearms and of having confiscated medical equipment.

The United Nations condemned the sentences.

BNA says the appeals session for the medics will start on October 23.
