Bahraini martyr Mohammad Al-Mokdad was laid to rest on Sunday in a mass funeral in Al-Bilad Al-Qadim, near the capital, Manama.
Al-Mokdad was martyred on Saturday as regime forces suppressed rallies in protest of execution of two activists Ali Mohamed Hakeem al-Arab and Ahmed Isa Ahmed Isa al-Malali.
February 14 Youth Coalition said Al-Mokdad inhaled toxic gases fired by regime forces.
The regime in Bahrain has executed al-Arab and al-Malali early on Saturday despite appeals by human rights groups to stop their execution.
They were convicted in a mass trial, with human rights groups saying they were tortured, prevented from attending their trial and sentenced to death in absentia.
The regime refused to hand over the bodies of the two martyrs, and prevented their families from attending their funeral.
