Authorities say it is likely there are no survivors after a hot air balloon carrying at least 16 people caught on fire and crashed in Central Texas.
The Caldwell County Sheriff's Office said in a statement Saturday that investigators are determining the number of victims and their identities.
Lynn Lunsford with the Federal Aviation Administration said in an earlier statement that the accident happened shortly after 7:40 a.m. Saturday near Lockhart, Texas, when the hot air balloon crashed into a pasture. Lunsford said there were at least 16 people on board.
Lunsford said that the FAA and the National Transportation Safety Board are going to the scene to investigate.
Emergency responders in Texas said the fire hit the basket portion of the hot air balloon.
The accident is likely to be one of the deadliest hot air balloon crashes on record. It comes about three years after 19 people, mostly Asian and European tourists, were killed in a hot air balloon crash in Luxor, Egypt.
The Federal Aviation Administration confirmed the Lockhart crash, about 30 miles (50 km) south of Austin. It did not offer any information on fatalities but said at least 16 people were on board the balloon.
The Caldwell County sheriff's office said it was working to determine the identities of those aboard.
More than a dozen police vehicles could be seen on pasture land at the site of the crash, in live video provided by Austin TV station KVUE.
The FAA said the crash took place at about 7:40 a.m. (1240 GMT) and that the National Transportation Safety Board had been notified.
Texas Governor Greg Abbott offered his condolences to those killed in the crash.
"Our thoughts and prayers are with the victims and their families, as well as the Lockhart community," he said in a statement.
Lockhart is a town of about 13,000 people near state parks and home to a variety of barbecue restaurants considered to be among the best in the state.
The crash in Egypt occurred after a mid-air gas explosion.
A year before that incident, a hot air balloon burst into flames and crashed in New Zealand, killing all 11 people on board in the country's worst air accident in more than three decades.
