Nearly a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.

Officials warned that the full extent of the catastrophe is unknown and unaccounted victims could still be found amid the massive piles of debris.

Texas Gov. Greg Abbott on Wednesday ordered state legislators to convene a special session on Monday as the death toll rose to at least 120 people and 172 reported missing in Fourth of July flooding in the Hill Country.
