SSUDAN-SUDAN-UNREST-BORDER

A bus departs from Ajuong Thok refugee camp in South Sudan, less than 100 kms away from the border with Sudan, on January 28, 2016. The bus will travel to Yida, the last village in South Sudan, before eventually crossing the border. Sudan ordered the reopening of the country's contested borders with South Sudan. Relations between Juba and Khartoum had been tense since South Sudan's secession split in 2011 under a peace deal that ended a bloody 22-year civil war, with disputes over several areas along the border. / AFP / ALBERT GONZALEZ FARRAN (Photo credit should read ALBERT GONZALEZ FARRAN/AFP via Getty Images)
