World leaders meeting at the Group of Seven summit in Canada called for a de-escalation of the worst-ever conflict between the regional foes.

U.S. President Donald Trump said his early departure from the G7 summit was owed to "much bigger" things than planning a ceasefire between Tel Aviv and Tehran. G7 leaders affirmed unified support for Israel and condemned Iran for being the "principal source of regional instability and terror.

The US president said he would end wars and now a vocal part of his support is urging him to stay out of this conflict.
