Priest killed and four injured in knife attack at Polish abbey

A priest has been killed and four other people injured in a knife attack in south-east Poland, officials have said. A 31-year-old Ukrainian man was arrested after the stabbings on the grounds of a Catholic abbey in the town of Jarosław. Polish President Karol Nawrocki said Thursday's attack "has shaken us all and demands a firm response from the state", while his Ukrainian counterpart Volodymyr Zelensky said "we are shocked by this evil". Reports in Polish media said the attacker first injured a priest in a nearby cafe, and then another four people inside the abbey itself. A police investigation into the attacker's motives is now under way. Polish police said four men and one woman were stabbed in the attack on Thursday morning on the abbey grounds.
