Camp Mystic, a Texas all-girls camp where 25 children and two counsellors died in last year's devastating floods, says it will not reopen this summer.

The camp said it had planned to host 800 girls to a different location this summer, which did not experience any fatalities, before withdrawing its application for a license.

"No administrative process or summer season should move forward while families continue to grieve, while investigations continue and while so many Texans still carry the pain of last July's tragedy," it said.

The withdrawal follows mounting pressure from parents of girls who died at the camp. Multiple investigations into the evacuation plans of the camp remain ongoing.

More than 130 people died in the central Texas floods over the 4 July holiday that shocked the nation and brought into sharp focus several emergency warning failures in the state.
