The Foreign Affairs Minister says the Middle East conflict is reaching an uncertain, dangerous and difficult point.

It's yet unknown whether Israel will heed America's warning not to respond to a barrage of missiles and drones launched by Iran.

The attack was in retaliation to Israel bombing Iran's embassy in Syria, and most of the hundreds of projectiles were intercepted.

Minister Peters says everyone who wants peace in the world has a clear message.

"And for goodness sake, don't escalate this matter. That includes the neighbourhood, the many Middle Eastern countries around the world as well."
