TAHTA, (Egypt): Egypt buried the dead Saturday from a train collision that killed at least 19 people and injured 185, according to a revised toll, as investigators probed the country's latest deadly rail crash.

Health Minister Hala Zayed told reporters that an initial toll of 32 killed in Friday's crash was revised down, while the number of injured rose from 165.

"After we honed in on the details of those killed and injured... at this moment there are 185 injured and 19 corpses and three bags of body parts," Zayed said, without giving further details.

Surveillance camera footage of the accident seen by AFP showed a speeding train barrelling into another as it rolled slowly down the tracks, sending a carriage hurtling into the air in a cloud of dust.

Most of those injured in Friday's crash that occurred in the Tahta district of southern Sohag province suffered fractures. The first victims were laid to rest early on Saturday with small groups of family and friends in attendance as residents, who appeared mistrustful of outsiders, kept the media at bay.

Other burials were expected to take place following mid-day Muslim prayers, an AFP reporter said.

President Abdel Fattah al-Sisi pledged tough punishment for those responsible for the crash, the latest in a series of rail accidents to plague Egypt. Such incidents are generally attributed to poor infrastructure and maintenance.
