A woman has been killed in an axe 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 afterwards.
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.
