The event was planned to take place in Switzerland
There appears to be an early threat to the peace deal between the US and Iran.
The so-called 'gentleman's agreement' appears to be in trouble already, after Iran and the US pulled out of the planned event in Switzerland.
It follows a punchy response from the US administration to Israeli criticism of the agreement - with Vice-President J.D Vance warning Israel not to attack 'the only powerful ally' it has left.
The White House is blaming logistical issues, but the announcement came after Iran was reported to have pulled out, because of strikes by Israel overnight.
Israel and Hezbollah exchanged fire overnight, with Lebanon's state news agency saying strikes were amongst the heaviest in recent weeks.
The Taoiseach says its 'regrettable' a peace deal in the Middle East seems to have to come a halt.
