Lightning struck at a Florida beach on Sunday, leaving eight people injured, police said.
The victims were struck at Clearwater Beach near Tampa on Sunday afternoon, according to the Clearwater Police Department.
The department said one person was hit by the strike directly and rushed to a nearby hospital in critical condition. Another person was treated for burns and three others were hospitalized as a precaution.
At least three others were injured, but refused treatment at the scene. Lightning was also blamed for at least three fires in the area on Saturday.

"Beachgoers should take cover and go to a safe place when lightning and thunder are present. As a reminder, Clearwater Fire and Rescue uses the phrase: when you hear the roar, go indoor," the fire department told ABC affiliate WFTS.
