A 17-year-old suspect killed two children and left nine others injured after attacking them with a knife at a dance workshop in Southport, England, Monday morning local time. Six of the injured children are in "critical condition."
According to Channel 3 Now, the suspect, who attacked mostly elementary-aged children, is Ali-Al-Shakati, a migrant who arrived in the UK by boat last year and was on MI6's security watchlist. Local police said two adults were also in "critical condition."
