 * White smoke signaled gas attack on Syrian town - REUTERS, April 5, 2017
 * ''The Syrian army jet that hit the town of Khan Sheikhoun at dawn dropped three conventional bombs and a fourth one that made little sound at impact but produced a cloud of white smoke, according to an activist observing from a nearby hilltop.
 * ''Hussam Salloum, a volunteer with an air raid warning service in rebel-held areas, said the Sukhoi-22 that attacked on Tuesday approached at low altitude, leaving behind three columns of dark smoke and the white cloud nearer to ground level.
 * ''"The smoke was white and thick," he told Reuters from Khan Sheikhoun. "The smoke began to spread out across the town, until there was a layer over the town," he said, sending a video filmed from an observation point that showed the plumes of smoke.
