The death toll from the flash floods that have wreaked devastation in Texas since Friday has passed 100 and is expected to rise further as more victims are found and more rain threatens to deluge the region.

Camp Mystic, the girls summer camp on the banks of the Guadalupe River in Texas, has confirmed that 27 children and counsellors died.

“Our hearts are broken alongside our families that are enduring this unimaginable tragedy. We are praying for them constantly,” a statement on the camp website read.
