Prime Minister Benjamin Netanyahu sought to rally international support for Israel at the United Nations General Assembly in New York, saying Israel will continue its wars until Hamas and Hezbollah are destroyed.
Netanyahu said the war in Gaza has to continue for now, while saying that he remains committed to returning the remaining hostages being held by Hamas.
In his speech, Netanyahu told world leaders that Iran is a common enemy that must be stopped, saying it wants to move back to a "dark age of war."
"Iran's aggression, if it's not checked, will endanger every single country in the Middle East and many, many countries in the rest of the world, because Iran seeks to impose its radicalism well beyond the Middle East," Netanyahu said.
