Florida shooting: Mother makes impassioned plea for 'action' from Donald Trump as funerals for victims begin - as it happened

New details are emerging about Nikolas Cruz, 19, the teenager suspected of carrying out America's latest deadly mass shooting as the country once more finds itself reeling in horror from another eruption of gun violence.

Students and teachers at the Marjory Stoneman District School in Parkland, Florida, are struggling to come to terms with the shock attack on Valentine's Day that saw a masked gunman enter its grounds bearing smoke grenades and kill 17 people with an AR-15 semi-automatic assault rifle, injuring many others.

As attention turns towards the identity of his victims and the heroism of those who survived the attack, America once again finds itself asking difficult questions about the future of its gun control laws. But Donald Trump has looked to place the blame on mental health provisions – apparently suggesting in a tweet that people who knew the killer should have done more to report him to the authorities.
