A woman has been killed in an ax attack at the University of Warsaw in Poland, police say. A man was severely injured in Wednesday's attack, they said. A 22-year-old Polish man has been arrested. His motives remain unclear. The university described the attack as a "huge tragedy". It described the woman as a member of staff — without giving other details — and the man as a security guard. The attacker entered the college campus at 18:40 local time (16:40 GMT). From there he proceeded into a lecture hall, according to a spokesperson for the district prosecutor. Few details have emerged about what happened afterward. Polish news outlet, Gazeta Wyborcza Daily says that the attacker was a third-year law student. There is no official confirmation. "We express our great sorrow and sympathy to the family and loved ones," the rector of the university said in a statement, adding that 8 May would be a day of mourning for the institution. — BBC
