Popularly known as ATT, the return of former president Amadou Toumani Touré is being demanded by activists of 13 opposition parties and leaders of civil society in Mali.
He has lived in exile in the past four years.
Touré lives in Dakar, the Senegalese capital, since the overthrow of his government in March 2012 by Captain Amadou Sanogo.
According to some media, the Malian government would like charges of “high treason” be brought against the former president.
He is accused of letting the North of the country fall into the hands of armed groups.
On Saturday, about 100,000 protesters, demanded for a “national dialogue on the security situation” in the north and central part of Mali.
