US President Donald Trump vowed that authorities will get to the bottom of a series of bombings in Texas, saying whoever carried them out was "very, very sick" on Tuesday.
His comments during a White House meeting with Saudi Arabia's Crown Prince Mohammed bin Salman came after a fifth package exploded on a conveyor belt in a FedEx package sorting facility near San Antonio.
The other four parcel bombs blew up in the Austin area.
"It's terrible," he said. "This is obviously a very, very sick individual or maybe individuals. These are sick people, and we will get to the bottom of it."
