On Sunday, the clashes broke out in the village of al-Muqsha, north of Manama, as Bahraini mourners held a funeral for 41-year-old Ja’far Jassim Radhi.
On Saturday, Bahraini activists found the body of Radhi at his home in a village near Manama.
The Bahraini victim died after inhaling tear gas fired by Saudi-backed regime forces in the area.
Another Bahraini protester, 27-year-old Sabri Mahfud, also died due to inhalation of tear gas fired by Al Khalifa forces north of the capital earlier on Sunday.
Saudi-backed Bahraini forces continue the violent crackdown on peaceful demonstrations across the country.
Scores of people have been killed in the crackdown on anti-regime demonstrations that broke out in February 2011, while thousands more have been arrested.
The protesters are demanding justice for the victims of the violence and the ouster of the Al Khalifa regime.
