WILMINGTON: A charter bus filled with junior college football players heading to a game crashed on an interstate highway in North Carolina on Saturday, killing four people on board and injuring more than 40 others, the state highway patrol said. The bus struck a bridge abutment on Interstate 74 near the town of Rockingham, about 70 miles east of Charlotte near the South Carolina border, in an accident triggered by a tyre blowout on the vehicle, the state police said in a statement. The bus was carrying a squad of community college football players from South Carolina to Fayetteville, North Carolina, for a game against a rival team there, school officials and police said.
