At least 20 people injured when Texas walkway collapses

At least 20 people were injured Thursday afternoon when an elevated walkway at a Texas beach collapsed, officials in Surfside Beach said.

There were no life-threatening injuries, officials in Brazoria County said.

A group from a faith-based summer camp was visiting the beach, which is about 65 miles south of Houston, when the structure collapsed.

Five people were taken by air to a Houston hospital, and 16 others went to a local hospital. The victims are 14 to 48 years old, officials said.

The cause of the collapse is unclear and under investigation.

NBC affiliate KPRC of Houston reported that part of the collapsed deck was tapped off, while other parts remained intact.
