Bahraini security forces have attacked the funeral of a teenage protester who was shot dead earlier this week.

Regime troops used tear gas on Saturday to disperse the mourners in the village of Sitra, south of the capital Manama.

Fourteen-year-old Seyed Mahmood Seyed Mohsen was killed by security forces during a demonstration on Wednesday.

He is one of the latest victims of brutal crackdown by the Al Khalifa regime against pro-democracy protests.

Scores of Bahrainis have been killed and hundreds of others injured and arrested in the ongoing crackdown on peaceful demonstrations.

Rights bodies have on various occasions slammed the Bahraini regime for using excessive force against peaceful protests.

On Friday, Amnesty International called on Manama to launch a prompt investigation into all cases of torture, ill-treatment and deaths that occurred during protests and in custody.

In a statement issued on its website, the group criticized Bahrain for the lack of transparency in investigations into deaths at protests.

It charged Manama with whitewashing the cases in which the security forces were accused of killing protesters.

In another statement issued on May 19, the rights group voiced concerns over the lack of reform of the judiciary in the Persian Gulf kingdom.

Since mid-February 2011, thousands of anti-regime protesters have held numerous demonstrations on the streets of Bahrain, calling for the Al Khalifa family to relinquish power.

On March 14, 2011, troops from Saudi Arabia and the United Arab Emirates invaded the country to assist the Bahraini government in its crackdown on peaceful protesters.
