Manama (Agencies): Three demonstrators were killed early on Thursday during police violence on protesters who continued pushing the government of Bahrain for reform and development.

The dead included an elderly man aged 60 to 70 and a young man, whose bodies were at the Salamynia Medial Hospital. Their bodies bore what appeared to be gunshot injuries, witnesses said.

The body of the third victim was still at the location of the protests, where medical staff who rushed to the scene and witnesses confirmed the death to mediaperson.

The deaths bring to five the number of protesters killed this week during protest demonstrations in Bahrain triggered by the ouster of former President Hosni Mubarak from Egypt late last week after 18 days of protests.

At least 45 people were being treated at the Manama hospital for wounds caused by teargas and shotgun fire, medical sources said.

Police encircled the square and opened fire without warning at about 3 am (0000 GMT), witnesses informed.

The crowd of thousands—estimates range from 5,000 to 20,000—included many women and children who joined the demonstrations which had run peacefully whole day following the funeral on Wednesday for an earlier victim.

In the ensuing time, everyone left the scene and police took control of the square.

Angry crowds in the meanwhile had showed up at the hospital, adding to a chaotic scene of shouting and screaming by hundreds of frightened people either seeking medical help or searching for loved ones.

A relaxed atmosphere surrounded demonstrations as thousands turned out for the funeral procession carrying 31 year-old Fadel al-Matrook to the cemetery on Wednesday. He was one of the two demonstrators killed in clashes with security forces in the protests which began Sunday evening.
