WASHINGTON -- Four U.S. Secret Service agents were involved in a head-on collision in New Hampshire that killed the driver of the other vehicle and injured six people, theSecret Service and media reports said.
The driver of the other car crossed into the oncoming lane and hit the vehicle carrying the on-duty agents, the Secret Service said in a statement on Wednesday.
It was not immediately known why the agents were in New Hampshire but leading Democratic presidential candidate Hillary Clinton, who has a Secret Service detail because of her status as former first lady, was campaigning there Tuesday night.
"Our personnel have sustained what is described as serious, but non-life-threatening injuries,"Secret Service Director Joseph Clancy said in the statement.
Two passengers in a Mercury Sable that hit the agents' Ford Taurus were hospitalized and the Sable's driver was killed, NBC News reported.
The accident occurred in Wakefield, New Hampshire, about 100 miles (161 km) north of Boston and near border with Maine, NBC said.
The Secret Service referred queries about details about the crash to the New Hampshire State Police, which could not be immediately reached for comment. The Wakefield Police Department said it would release a statement later on Wednesday.
Storms and harsh winter weather hit New Hampshire on Tuesday, forcing Republican presidential candidate Jeb Bush to cancel a campaign event.
New Hampshire holds one of the first primary elections in the run-up to the November 2016 presidential election, making it a popular place for candidates to campaign this time of year.
