A lawyer acting for Zimbabwean rights activist Jestina Mukoko says his client is in the process of suing the government for violating her constitutional rights.

Terror charges against Mukoko and eight others were dropped in the Harare Supreme Court on Monday.

They were accused of plotting to overthrow President Robert Mugabe.

She testified during a bail hearing late last year that she was tortured and assaulted during detention.

Her lawyer Andrew Makoni said his client would be seeking compensation.

"The matter is pending in the High Court of Zimbabwe. We are hoping the matter will also be attempted in the high court."
