Police reportedly fired tear gas and live ammunition at the demonstrators on Wednesday, but the number of casualties is unclear, Saeed al-Shehabi, leader of Bahrain Freedom Movement, told Al Jazeera.
Shehabi said protests have been reported on Tuesday evening and Wednesday morning in at least five neighborhoods, mostly outside of the capital Manama, including in Diraz, Sitra and Huwaidrat.
"The situation is as tense as ever, and the crackdown is also severe," the UK-based activist said.
Hussain Radhi of Bahrain Center for Human Rights said that clashes also took place in the districts of Abu Saiba, Aldaih, Mameer, Aleker and Bilad Al Qadeem. There was no information about injuries.
Images posted on social media showed security forces in full gear standing next to several police cars.
Pictures also showed masked protesters hurling rocks at police as they walked through a street engulfed in tear gas.
In a video clip posted on Twitter by the London-based Bahraini television channel LuaLua, security forces were seen firing tear gas as they engaged in a running battle with protesters.

In January, a Bahraini court also affirmed a two-year jail sentence against protest leader Nabeel Rajab.
Shehabi, however, said he was surprised that people have continued to protest.
“Day in and day out, there have been protests and demonstrations,” he said.
Despite the threat of imprisonment of up to five years for “spreading false news,” Shehabi also said that people have been posting images on social media showing the ongoing protests.
For years, tensions have been running high in the kingdom over a heavy-handed crackdown by the regime.
Starting in 2011, Shia-led protests erupted across the country, forcing neighboring Saudi Arabia to intervene on behalf of Bahraini rulers.
Authorities have refused to listen to opposition demands for reforms, including the establishment of a “real” constitutional monarchy with an elected prime minister independent of the ruling royal family.
In response, authorities ordered the imprisonment of thousands of activists and stripped Shia spiritual leader Isa Qassim of his nationality.
Saudi Arabia has accused Iran of encouraging its Shia population to rise against Bahrain’s Sunni rulers, allegations that Tehran has denied.
Meanwhile, the Persian Gulf Center for Human Rights called on the international community on Wednesday to “apply serious pressure” on Bahrain to release journalists and human rights activists, some of whom are facing lifetime jail terms.
