Matthew McConaughey has said the spate of mass shootings across America is 'an epidemic we can control' as he paid tribute to the victims of the atrocity in his Texas hometown of Uvalde.
At least 19 children and two adults have been reported dead after a teenage gunman opened fire at Robb Elementary School in Uvalde on Tuesday.
The devastating shooting is the deadliest at a US primary school since the infamous Sandy Hook shooting in Newtown, Connecticut, where 20 children and six adults were killed in 2012.
