Two foreign workers have been killed and a third seriously injured by a series of terrorist bomb blasts in Bahrain. The nationalities of the dead men are not known, but police said there were five explosions caused by home-made devices in two areas of the capital Manama earlier today.

One of the men died at the scene when he kicked a device in Gudaibiya. The second died in hospital after being injured by an explosion near a cinema. A third explosion in Adliya injured another man, working as a cleaner. Officials said the victims were Asian. The head of Capital Governorate Police urged all residents of Bahrain not to touch strange objects and to notify the authorities if they saw one.

Bahrain has been at the centre of escalating unrest since 2011. As the government have clamped down on free speech and public gatherings prompting condemnation from human rights groups. Opposition supporters have been demanding more democracy and an end to what they say is discrimination against the majority Shia Muslim community by the Sunni royal family. An investigation into the cause of the blasts, described as an "act of terrorism," is currently under way.
