Security officials arrested an Islamist opposition figure in his home in Khartoum on Monday. Hassan al-Turabi was taken into custody a day after he called for a “popular revolution” if the price increases on basic goods were not reversed. In an interview with AFP al-Turabi had said that similar developments to Tunisia could unfold in Sudan. He has been imprisoned and released several times since 2000 when he left Omar Hassan al-Bashir’s ruling party.
