Around 240 balloons were displayed at Götaplatsen in Gothenburg on Sunday, one for each hostage taken by Hamas.
"We want to show that we think about them, that we support them and that we want them to be set free," Stutzinsky said.
"Does not take a stand for or against war"
In a press release from the Jewish community in Gothenburg, they write that the purpose of the manifestation is not to take a stand for or against war, but to demand that the hostages be released.
Sweden recently abstained from voting for a humanitarian ceasefire in the UN vote, because the resolution does not clearly condemn Hamas's attack on Israel and does not refer to Israel's right to defend itself against terrorists, according to Foreign Minister Tobias Billström.
Opinions differ
What do you think about Sweden abstaining?
"I think it was good. A ceasefire now is an invitation to Hamas to slaughter Jews again, says Allan Stutzinsky.
But according to the Jewish association, Jews for Israeli-Palestinian Peace (Jipf), which has about 100 members in Sweden, this is the wrong way to go.
Staffan Granér is one of the spokespersons for the association. He thinks Hamas should release the hostages unconditionally. At the same time, he thinks that Sweden should have voted for the humanitarian ceasefire.
"The reasonable thing to do is to take a clear stand against the use of this type of excessive force against civilians," he says.
"As long as the hatred and threats remain, the defense is defensible," says Allan Stutzinsky.
