Khartoum, Aug 2 (SPA) -- Sudanese armoured vehicles deployed at strategic points of the capital on Tuesday after a day of violence sparked by the death of southern leader John Garang claimed at least 36 lives. The streets had emptied during a curfew imposed between 6 p.m. and 6 a.m. (1500-0300 GMT) after southerners on Monday rampaged through Khartoum angered by the death of Garang who led them to a peace deal after two decades of war with the north, according to a report of Reuters. A security official, who declined to be named, said the death toll from Monday's rioting had reached 36. He said more than 100 people were in hospital with injuries from the riots that were some of the worst in the capital in recent years. Cars returned to the streets on Tuesday but the city remained relatively calm amid a heavy security presence. Residents said some emergency vehicle sirens sounded, but it was not immediately clear where the vehicles were headed. Garang, a key figure in a January peace deal and leader of southern Sudan's rebel movement during its two decades of war with the government in Khartoum, died when the helicopter he was traveling in went down in bad weather at the weekend. The death of Garang, who was sworn in as Sudan's first vice-president on July 9, was announced on Monday. --SPA 1448 Local Time 1148 GMT www.spa.gov.sa/280593
