Police are preparing to arrest the hospitalized driver of an SUV that slammed into a crowd, killing eight people waiting for a bus Sunday outside a migrant shelter in the border city of Brownsville, Texas. At least 10 others were injured, authorities said.

With no bench at the unmarked city bus stop, some of the victims were sitting on the curb around 8:30 a.m. when the driver hit them, surveillance video from the Bishop Enrique San Pedro Ozanam Center showed. Brownsville police investigator Martin Sandoval, who confirmed the latest death Sunday evening, said police did not know whether the collision was intentional.

Shelter director Victor Maldonado said the SUV ran up the curb, flipped and continued moving for about 200 feet (60 meters). Some people walking on the sidewalk about 30 feet (9 meters) from the main group were also hit, Maldonado said. Witnesses detained the driver as he tried to run away and held him until police arrived, he said.

Under a set of white tents at the U.S.-Mexico border in Brownsville, Texas, dozens of Venezuelan men waited. Some sat on curbs and others leaned on metal barricades. When the gates eventually opened, the long line of men filed slowly up the pedestrian pathway to the bridge and across the Rio Grande River to Mexico.

In the past few weeks, U.S. Customs and Border Protection officials have been facilitating these expulsions three times a day as roughly 30,000 migrants, mostly from Venezuela, have entered the U.S. in this region since mid-April. That’s compared with 1,700 migrants Border Patrol agents encountered in the first two weeks of April.

In the other end of the state, in El Paso, officials are dealing with another surge of migrants and worry that thousands more are waiting to cross.

All this comes as the U.S. is preparing for the end of a policy linked to the coronavirus pandemic that allowed it to quickly expel many migrants, and it spotlights concerns about whether the end of the immigration limits under Title 42 of a 1944 public health law will mean even more migrants trying to cross the southern border.

The Biden administration is working on new regulations that would require airlines to compensate passengers and cover their meals and hotel rooms if they are stranded for reasons within the airline’s control.

The White House said President Joe Biden and Transportation Secretary Pete Buttigieg would announce the start of the rulemaking process Monday.

The rulemaking pledge continues a push by the Democratic administration to require airlines to improve customer service, and it comes just weeks before the start of the peak summer travel season.

The aim of the rules would be, for the first time, to require airlines to pay compensation beyond a ticket refund and to cover expenses that consumers incur, including rebooking on another flight, if the airline causes a cancellation or significant delay.
