Maryam al-Khawaja, head of the foreign relations office at the Bahrain Centre for Human Rights, said: "The government promised changes last year, but no changes have taken place because there is no incentive to make them. And tortures are still taking place.
"The government want the message to go out that, it is business as usual. But today armoured vehicles went into residential areas for the first time since last year's martial law ended in June.
