On Sunday hundreds of mostly Venezuelan migrants entering the country through Mexico were stopped by U.S. officials. Frustrated with problems using a new U.S. government app to schedule an appointment to seek asylum, the large group broke through Mexican lines at the border city of Ciudad Juarez demanding asylum but could not breach the barriers. Many of the migrants were accompanied by small children. The crowd eventually withdrew after some pushing and shoving with the officials. Some headed down to the banks of the Rio Grande where U.S. immigration officials arrayed on the other side and monitored the crowd.
