Yahoo is accused of helping China identify dissidents
Internet users are being urged to stand up for online freedoms by backing a new campaign launched by human rights group Amnesty International.
Amnesty is celebrating 45 years of activism by highlighting governments using the net to suppress dissent.

The campaign will highlight abuses of rights the net is used for, and push for the release of those jailed for speaking out online.

It will also name hi-tech firms aiding governments that limit online protests.
