Opposition and human rights groups have criticised a new Ethiopian anti-terrorism law saying it doesn't go far enough in terms of reform.The law - passed on Thursday - replaces old legislation which described as terrorism any gathering that disrupted public services.It now says workers have the right to strike even if they do disrupt public services.The new law also removes text used to authorise the arrests of dozens of journalists and opposition politicians.Amnesty International said the legislation still had potential for abuse, but had some pro-human rights elements.
