Swedish Prime Minister Ulf Kristersson condemned “an attempted attack” against the Israeli embassy in Stockholm, after an object found outside it was destroyed by the bomb squad on Wednesday, writes The Guardian.

Police said a “live” device had been found by staff on the embassy premises on Wednesday, calling it “a dangerous object”, although they did not specify what it was.

“This is very serious. An attempted attack on an embassy is an attack both on those who work there and on Sweden”, Kristersson said in a social media post, adding police and Sweden’s security police were investigating “who is or who are responsible”. The prime minister added that surveillance of the embassy and of Jewish institutions in Sweden had been tightened.

After the area around the object was closed off, the national bomb squad was called to the scene and made the decision to destroy the object. “Our assessment is that it was live,” a police spokesperson said.
