A bus crash in the Mexican state of Oaxaca killed 16 people on Friday, according to local authorities, who say most of the passengers were migrants. Three children and two women are among the victims, all of whom are from Venezuela and Haiti, the Oaxaca state attorney general said. At least 27 people were injured and transported to nearby hospitals. Authorities are investigating the cause of the accident, which took place at 5 a.m. local time (7 a.m. ET). The Oaxaca state attorney general’s office had first said 18 people died in the crash, then revised its count late on Friday evening. The tragedy follows the deaths of at least 10 Cuban migrants, including a child, on Sunday, when the truck they were traveling in also overturned in southern Mexico, according to local authorities. US and Mexican officials have struggled to respond to the arrivals, with Washington putting increasing pressure on Mexico City to shoulder more responsibility for people crossing its territory. On Thursday, senior officials in the Biden administration said the US would restart deporting Venezuelans directly to Venezuela in an attempt to curb the record influx, marking a major shift in policy.
