I think that both I and others with me are celebrating it, he says in connection with a debate in the Riksdag.
He believes that the killing could be a step closer to Hamas being defeated.
Hamas has been a plague and a scourge for both Israel and the Palestinians for very many years, so it's incredibly gratifying.
If Yahya Sinwar had been arrested and put on trial, Forssell would have been even happier.
Then I would have popped the champagne, he says.
"Must rush forward"
Foreign Minister Maria Malmer Stenergard (M) says that she personally does not celebrate when people die.
No, I never celebrate when people die.
You'll have to ask him, she says about Forssell's statement.
In the Riksdag debate, the Foreign Minister reacted to Social Democrat Ola Möller likening Israel's and Russia's ambassadors.
Möller questioned why Israel's ambassador was "strutting around" in the Riksdag last week, while Russia's ambassador was not welcome.
Then it would have taken hell to break loose. Israel's ambassador is still welcome, but not Russia's – that's not playing by the same rules based on international law, he said.
Maria Malmer Stenergard says she was taken aback by the statement.
It would be interesting to hear if it's the Social Democrats' opinion or just Ola Möller's misstep.
"Tasteless, disgusting"
The Foreign Minister does not think that the Social Democrat takes the terrorist attack that Hamas carried out against Israel on October 7, which started the war, seriously.
Because there, Israel also has a right to defend itself. Unlike Russia, which has completely unprovokedly invaded a peaceful neighboring country. Therefore, it's not comparable. It's tasteless and disgusting.
Ola Möller later writes in a comment that he regrets his statement. Israel, like Russia, commits violations of international law and international law, "but the background is different" and the comparison "was over the line".
"I went too far", Möller writes.
On the question of how Hamas leader Sinwar's death can affect the war, Maria Malmer Stenergard answers that it's difficult to say.
He was the brain behind the disgusting terrorist attacks on October 7. There is reason to once again raise the demand that hostages must be immediately and unconditionally released, she says.
Does this mean that Hamas is defeated?
It's too early to speculate about that, we'll have to follow the development very closely.
