The legislators also praised police "for maintaining order" but said they must "carry out their duties within the respect of law, human rights and public freedoms."
An uneasy calm returned to majority Shiite areas in Bahrain on Monday after a week of clashes between police and protesters, during which security forces used teargas and fired rubber bullets in Shiite villages.
The disturbances erupted after the death on December 17 of protester Ali Jassem after an opposition demonstration.
Jassem, 22, died in hospital after being taken ill at his home following the protest at Jid Hafs during which he inhaled teargas, a Shiite activist told AFP on condition of anonymity.
The interior ministry said an official medical examination concluded he died from a sudden drop in blood pressure, the Bahrain News Agency (BNA) reported.
Shiites — the majority group in the small Sunni Muslim-ruled Gulf monarchy — took to the streets to seek compensation for what they said were human rights violations carried out between 1980 and 1990.
