Police in Austria say a 23-year-old man has admitted carrying out knife attacks in Vienna which left four people seriously injured on Wednesday evening.

The man, an Afghan national, has denied a political motive for the attacks.

Three members of the same family were hurt in the first attack at Nestroyplatz at 19:45 (18:45 GMT) and an unrelated man, 20, was stabbed nearby around half an hour later.

The suspect reportedly told police he had been in a "bad, aggressive mood".

The 23-year-old said he had attacked the family - parents and a teenage daughter - because he was angry about his situation in life, Vienna police said in a statement (in German).
