Two people have been killed and 41 injured after a bus carrying relief workers crashed in Louisiana on Sunday.
Three of the injured are in a critical condition in hospital.
The bus was travelling to Baton Rouge on Sunday morning to deliver flood relief aid when the crash happened, according to NBC News.
The state is currently in the midst of an extensive rescue effort after 2.5ft of rain fell earlier this month.
At least 13 deaths have been attributed to the flooding and more than 60,000 homes have been damaged.
In a statement on Sunday afternoon, parish president Natalie Robottom confirmed a fire chief was among the dead.
She said: "This was a horrific accident and one that is still very active.
"This type of loss will affect the entire department and they will have our full support as they deal with the grief of losing a comrade.
"It is heartbreaking, especially after this same group of individuals helped to guide St. John the Baptist Parish safely through Hurricane Isaac, the February tornado and the flood event last week", she added.
