Twin gun massacres that left 29 people dead in the US in less than 24 hours have led to more outrage - and mourning - in America.
On Saturday afternoon, a gunman opened fire inside a Walmart in El Paso, Texas, killing 20 people and injuring more than two dozen.
Just hours later, at 1am local time (6am BST) another gunman attacked the centre of Dayton, Ohio, killing at least nine people and injuring 16 others.
Last Sunday, a six-year-old boy and a 13-year-old girl were among three people killed when a gunman opened fire at a California food festival.
The three recent mass shootings have sparked calls for tighter gun control in the US as they join a growing list of deadly attacks in the last two years.
