Amid rescue efforts after massive flooding in Texas, an illegal drone struck a helicopter involved in an emergency response in Kerr County.

Torrential rains before dawn on Friday deluged the Guadalupe River, which burst its banks and killed dozens of people, leaving behind mangled piles of debris, trees and cars.

Teams from Missouri, Florida and Mexico are aiding in search-and-rescue efforts as the weather is expected to improve over the next couple days.
