Two people were killed in two Copenhagen shootings on Saturday, which police believe were carried out by the same suspect. One person died in an attack at an event promoting freedom of speech and another, a security guard, in the assault at a nearby synagogue.

"This wave of attacks and the murderous anti-Semitic assaults that are part of it is expected to go on," Netanyahu said at the start of his weekly cabinet meeting, describing the shootings as "extremist Islamic terrorism."

"Israel is your home. We are preparing and calling for the absorption of mass immigration from Europe," Netanyahu said in a statement, News 24 reports.

The Israeli leader made similar remarks in January after the Paris attacks.

"To the Jews of Europe and to the Jews of the world I say that Israel is waiting for you with open arms," Netanyahu said.

Meanwhile Iranian Defense Minister Brigadier General Hossein Dehqan said the Takfiri terrorist groups are serving Israel's interests and security by fighting a proxy war in the region, FNA reports.

"The Takfiri stream is fighting a proxy war for Israel and it is currently at the service of that regime's security," Dehqan told reporters in Tehran on Sunday.
