Several political parties in Mali have condemned the arrest and detention of the fourth vice-president of the National Transitional Council (CNT), the country's interim parliament.

Issa Kaou N'Djim was arrested at his home in the capital, Bamako, on Tuesday and is due to go on trial on Friday.

According to local media, he was accused of "criminal behaviour" after making "subversive remarks" on social media against Prime Minister Choguel Maïga.

Mr N'Djim is a supporter of the interim president, Colonel Assimi Goïta, but critical of Mr Maïga, who he accuses of mismanaging Mali's transition to civilian rule.
