Prime Minister Cheick Modibo Diarra of the transitional Malian government announced resignation and dissolved the cabinet early Tuesday, state TV reported.

Appearing on state TV, Diarra did not elaborate on reasons for his resignation.

Military sources said Diarra was arrested earlier Tuesday by troops supportive of ex-coup leader Amadou Sanogo.

The prime minister was preparing to travel to Paris late Monday for medical examination when he was detained, the sources added.

Diarra, who had been acting prime minister since April, had called for international military intervention in northern Mali, which has been run by rebels since June.

Mali has been dealing with diverse security, economic, political and humanitarian challenges since January after a fighting between government forces and al-Qaida-linked rebels broke out in the northern part of the country.
