The G7 summit in Alberta, Canada will congregate for a third day today - with the notable exception of US President Donald Trump. The US president left the economic bloc's summit ahead of schedule last night, with the White House confirming he had to see to affairs at home as Israel's strikes on Iran continue.

Before leaving, President Trump joined the other leaders in issuing a statement saying Iran "can never have a nuclear weapon" and calling for a "de-escalation of hostilities in the Middle East.

Ukraine’s leader was denied a meeting with his most powerful ally, after Donald Trump left the summit a day early.
