Sweden is upset about Israel's attack on a United Nations base in southern Lebanon Tuesday night, which killed four international observers, a government minister said on Wednesday.

Swedish Foreign Office Minister Carin Jaemtin, deputizing for Foreign Minister Jan Eliasson, said the Swedish government has called for an end to the latest military action since it started and the escalation in violence is unacceptable.

The minister said the strikes must stop and all parties involved need to show restraint.

Meanwhile, a number of Social Democratic parliamentary candidates in Sweden are calling on the government to expel Israel 's ambassador in Stockholm as a show of protest against the Jewish state's attacks on Lebanon.

The nine candidates, who are standing for Sweden's parliament, the Riksdag, in the general election to be held on September 17, accused the government of inaction.

But Carin Jaemtin dismissed the call to send the Israeli ambassador packing.

"I think that would be a completely crazy measure to take. The right way forward is diplomacy and talks, and I hope that we will be able to continue to talk with the Israeli ambassador in Stockholm," she said.
