Investigators say that the attacker who opened fire on pupils as they were praying at a church in Minneapolis was 'obsessed with the idea of killing children'. Robin Westman, who killed two children and injured 18 others, did not seem to have any specific motive, according to Minneapolis Police Chief Brian O'Hara. The attacker 'appeared to hate all of us,' the chief said on Thursday, adding: 'More than anything, the shooter wanted to kill children.' The murdered children have been identified by family as Fletcher Merkel, eight, and Harper Moyski, 10.

'Yesterday, a coward decided to take our eight-year-old son Fletcher away from us,' his father, Jesse Merkel, told reporters. 'We will never be allowed to hold him, talk to him, play with him and watch him grow into the wonderful young man he was on the path to becoming,' he said. 'Fletcher loved his family, friends, fishing, cooking and any sport that he was allowed to play.' 'Please remember Fletcher for the person he was and not the act that ended his life,' he continued, choking back tears. 'Give your kids an extra hug and kiss today. We love you, Fletcher. You'll always be with us.'

The parents of Harper Moyski, Michael Moyski and Jackie Flavin, said in a statement that their daughter 'was a bright, joyful, and deeply loved 10-year-old whose laughter, kindness, and spirit touched everyone who knew her'. They added that the family hopes 'her memory fuels action' to stop gun violence.

Officials have released few details so far about the suspect's background, but say she previously attended the church's school and had a mother who had worked there. The 23-year-old suspect is believed to have approached the side of the Annunciation Church, which also houses a school, and fired dozens of shots through the windows using three firearms. Police also found a smoke bomb at the scene.

Witnesses have described seeing children bleeding as they fled from the church, begging for help from strangers. 'The shooter expressed hate towards many groups, including the Jewish community and towards President Trump,' said acting US Attorney General for Minnesota Joseph Thompson. The attacker, who died at the scene of a self-inflicted gunshot wound, left a note, but officials said a definitive motive may never be known.

FBI Director Kash Patel described the attack as 'an act of domestic terrorism motivated by a hate-filled ideology.'

'No family should ever have to endure this kind of pain.... Change is possible, and it is necessary so that Harper's story does not become yet another in a long line of tragedies.'

In the wake of the attack, several lawmakers, including the Minneapolis mayor, have called for the state to enact a ban on assault weapons, emphasizing the ongoing safety concerns surrounding gun violence in the United States.
