Caitlin-Rose McMullan died after beingin Castledawson, County Londonderry, in March.
Stella McMullan said her daughter may not have lost her life if there had been "bus safety in place".It comes as plans are in place to bring forward legislation to prohibit drivers overtaking school buses which have stopped to drop off or pick up their passengers.Ms McMullan said Caitlin-Rose was "blindsided" when she walked out between two buses and "couldn't see traffic coming".
"My daughter unfortunately died on a 60mph road with no footpath, with no bus shelter and basically got off her bus on a mucky, grass verge - so the bus pass that she [was] issued, I thought was a death sentence," she said.Ms McMullan was speaking at Stormont where other families who lost loved ones in similar circumstances also shared their support for any legislation to tighten road safety laws.
Calls have been made for new laws to improve school bus safety in Northern Ireland since Caitlin-Rose's death.
Ms McMullan said there are "no words to describe" how poor the safety around the bus stop was."It is clear that this is a targeted act of violence and the FBI is investigating this as an act of terrorism," Mr Michalek said. "Sadly, attacks like this are becoming too common across the country."
The attack is the second high-profile act of violence in the US in the last two weeks related to the conflict in Gaza.A man who shouted "free Palestine"
outside a Jewish museum in Washington DC on 22 May. The incident happened at a networking event organised by a Jewish organisation.Colorado's Attorney General Phil Weiser said that from what officials know the attack "appears to be hate crime given the group that was targeted".
