Authorities in northeast Kansas say two people have died after a communications tower they were working on collapsed.

The Pottawatomie County sheriff’s office says four workers were at the site near Blaine when the tower fell around 9:30 a.m. Tuesday. Another communications tower also collapsed.

Emergency personnel said one of the towers was recently built and the other was an older structure that was being dismantled by the two workers who died.

Both victims were more than 250 feet above the ground when the tower fell. One was pronounced dead at the scene and the other at a hospital.

The workers’ names and details about the towers were not immediately released. The two workers on the ground were unhurt.

Blaine is located about 50 miles northwest of Topeka.
