Good morning.
Austrian police are still searching for at least one suspect after a multiple gun attack overnight in the capital, Vienna, that killed four people.
Seventeen other people have been wounded - some seriously - after gunmen opened fire at six different locations in the city centre on Monday evening.
One attacker was shot dead by police, officials said, and one was arrested.
Interior Minister Karl Nehammer described the assailant killed by police as an "Islamist terrorist".
Two of those who died in the random shooting were women and two were men. One of the women was reportedly a waitress. The second woman died of her wounds in hospital overnight, reports said.
The victims were in a city centre area busy with people in bars and restaurants, near Vienna's central synagogue, but it is not yet clear if that was the target.
Addressing a news conference, Mr Nehammer said the heavily armed gunman killed by police was an Islamic State (IS) sympathiser and that his home had been searched and video material seized. Police tweeted that he had been wearing a fake explosive belt.
Earlier, Mr Nehammer said at least one "heavily armed and dangerous" attacker was believed to be still at large. Officials were quoted as saying there could have been as many as four attackers. The interior minister urged people to avoid central Vienna and told parents to keep their children home on Tuesday if they could.
