Britain's David Cameron reveals plans for controversial counter-terrorism bill

Britain's prime minister has pledged to take a tougher stance on extremism, revealing controversial plans to confront what he called "poisonous Islamist extremist ideology."

David Cameron says that for too long, Britain has been "passively tolerant" and that has helped foster extremism.

Cameron on Wednesday set out his intention to introduce a new counter-terrorism bill. Full details of the plans have not yet been unveiled, but they are expected to include new orders to ban extremist organizations that publicly use hate speech. Police are also expected to get powers to seize the passports of those suspected of plotting to travel abroad to fight.

The plans were immediately criticized by opposition leaders and rights groups, who say that the measures are authoritarian and an attack on free speech.
