The Brussels residents are not exactly 'happy' about Donald Trump's arrival

The decision came as leaders of the military alliance are gathered in Brussels to discuss burden-sharing and terrorism as part of an effort to show U.S. President Donald Trump that the military alliance he once called "obsolete" is still relevant today.

Earlier, he was granted a short private audience with the Pope at the Vatican.

North Atlantic Treaty Organisation chiefs have already agreed to his request to join the US-led coalition against ISIS in Iraq and Syria.

Trump appeared to be greeted warmly by the leaders, despite his past comments publicly cheering the United Kingdom's vote to leave the European Union last summer and slamming the alliance during his transition as "a vehicle for Germany". The American people are doing a lot for your security, for joint security.

One European official told BuzzFeed News their government had rather low expectations as far as the U.S. position on multilateral questions like trade and climate was concerned, and weren't expecting the USA to change its position significantly at the G7 Summit in Sicily.

Asked about Trump not explicitly affirming USA support for Article 5, White House press secretary Sean Spicer said: "It goes without saying".

After Tusk, Trump met European Commission President Jean-Claude Juncker and they were later joined by European Parliament President Antonio Tajani and the EU's top diplomat Federica Mogherini, Efe news reported.

An EU source said Trump had told Tusk and Juncker he was now anxious that Americans may lose jobs as a result of Britain leaving the EU in 2019: He "expressed concern that jobs in the US would be lost because of Brexit", the source said.

"But some issues remain open, like climate and trade".

Marine Le Pen, the far-right candidate who Macron defeated to win the French presidency, said before the election that she was best placed to defend France's interests in what she called the "new world" of Trump and Russia's Vladimir Putin. European Union sources said that during the meeting there was support for setting up a working group on trade issues, as well as for working together with other countries to tackle unfair trade practises.

On global affairs, they had an "exchange of views" that covered the "promotion of peace in the world through political negotiation and interreligious dialogue", and highlighted the need to protect Christian communities in the Middle East.

Trump, who unlike other leaders at the summit is not planning to address reporters, did not respond to shouted questions as to whether the United Kingdom can trust the USA with sensitive material. We had a fantastic meeting and we had a fantastic tour, it was really lovely. The other leaders are divided over his spending demands, as well as over how much intelligence to share with Trump's troubled administration.

Mr Trump responded by saying: "We can use some peace".

He arrived in Europe from Israel and the Palestinian territories, where he vowed to try to achieve peace in the region.

Mr Trump will end his tour on the Italian island of Sicily at the G7 summit on Friday.
