TEHRAN (FNA)- Bahraini security forces beat to death a 16-year-old protester as pro-democracy demonstrations against the ruling al-Khalifa regime have intensified in the Persian Gulf Arab country.

Bahrain's police fired teargas on Tuesday to disperse protesters who staged anti-government demonstrations to call for the freedom of political inmates.

Bahraini regime forces attacked anti-government demonstrators in Bahrain's Northeastern island of Sitra.

The Saudi-backed forces used tear gas to disperse the protesters on Tuesday.

A similar demonstration was also held in Sitra on Sunday.

Anti-government protesters have been holding peaceful demonstrations across Bahrain since mid-February 2011, calling for an end to the Al Khalifa dynasty's over-40-year rule.

Violence against the defenseless people escalated after a Saudi-led conglomerate of police, security and military forces from the Persian Gulf Cooperation Council (PGCC) member states - Saudi Arabia, Kuwait, the United Arab Emirates, Oman and Qatar - were dispatched to the tiny Persian Gulf kingdom on March 13, 2011, to help Manama crack down on peaceful protestors.
