Bahraini protesters attacked a police station with petrol bombs on Thursday and riot police responded with teargas and stun grenades after a funeral march for a man killed in clashes during the Gulf Arab state's Formula One race last week.
Petrol bombs set the police station's wall ablaze and the clashes spilled onto a main highway, holding up traffic for up to an hour, Reuters witnesses said.
The clashes, in the Manama neighbourhood of al-Bilad al-Qadeem, took place after thousands of mourners visited the grave of Salah Abbas Habib, 36, who was found dead on Saturday after disappearing during fighting between protesters and police.
Demonstrators hurled petrol bombs during nightly clashes with the police who responded by firing teargas and rubber bullets.
Crowds of protesters hurled petrol bombs at police who fired tear gas back in Bahrain on Saturday on the eve of the Grand Prix.
Protesters have clashed with police in Bahrain as F1 bosses remained defiant and the country's leaders refused to "empower extremists."
