Austria arrested a 14-year-old on Feb. 10 on suspicion of planning a terrorist attack on Vienna's Westbahnhof train station and found items at his home suggesting he supported Islamic State, Austrian news agency APA reported on Wednesday.
The report follows a knife attack in the southern town of Villach on Saturday, in which a 23-year-old Syrian refugee is suspected of having killed a teenager and wounded five people. That man was rapidly radicalized after watching Islamist videos on social media, Austrian authorities have said.
