Iranian president accuses Israel of wanting to provoke a 'wider conflict'
Iran's recently elected President Masoud Pezeshkian said Israel was seeking to expand the regional conflict by provoking Iran to join its allies Hezbollah and Hamas.
"We do not wish to be the cause of instability in the Middle East as its consequences would be irreversible," he said in New York, where he was set to attend the UN General Assembly.
"It is Israel that seeks to create this wider conflict," he said. "They are dragging us to a point where we do not wish to go."
Pezeshkian also pointed to US appeals for Iran not to retaliate so that efforts for a peace deal could succeed.
"But we never reached that elusive peace. Every day Israel is committing more atrocities and killing more and more people — old, young, men, women, children, hospitals, other facilities," he said.
Israel announces state of emergency across country
