Police blasted water cannons at protesters in Northern Ireland who set small fires and hurled bricks, rocks and bottles at them during a second night of violence Wednesday over a brutal stabbing on a Belfast street.Demonstrators wearing masks tore bricks from the walls outside homes and smashed pavements with sledgehammers to toss at riot police. In one place, the unruly crowd used sections of a dismantled picket fence to take cover on the street.The clashes with police came several hours after a 30-year-old man from Sudan appeared in a Belfast court charged with attempted murder in a stabbing attack that left a man seriously injured and triggered anti-immigrant violence.Hadi Alodid, 30, was ordered held in jail after appearing by video in Belfast Magistrates’ Court, where a detective said he blinded Stephen Ogilvie in the left eye during the knife attack. He was also charged with possessing a knife and threatening to kill a radiographer while being treated for a hand injury after the assault.When police arrived at the crime scene, they found Alodid on the man, armed with a kitchen knife, the detective said. Alodid later told hospital staff: “I’ve killed someone, I don’t know if they are dead,” and said: “I will kill you”.He refused legal representation through an Arabic interpreter and did not enter a plea.
