US President Donald Trump ended his nine-day overseas journey on Saturday, addressing US troops at a campaign-style rally before leaving for the US.
During the trip, Trump had meetings with Middle Eastern leaders while demanding that NATO allies pay towards the defence budget.
At a Group of Seven summit in the resort town of Taormina on the island of Sicily, Trump told his other six allies that he needed more time to make up his mind on the Paris climate agreement.
I will make my final decision on the Paris Accord next week!

In a hangar at Naval Air Station Sigonella, which is also on Sicily, Trump was introduced by his wife Melania.
Trump said he had helped forge more international cooperation in the fight against militants, a threat he said was underscored by a suicide bomber in Manchester, England, and the killing of Coptic Christians in Egypt.
"It was a tremendously productive meeting where I strengthen American bonds," said Trump.
"We have great bonds with other countries and, with some of our closest allies, we concluded a truly historic week."
Trump said his appeals to NATO allies to pay more was working.
"Money is starting to flow in," he said. "It's only fair to the United States. We're behind NATO all the way. But we want to be treated fairly."

No end-of-trip news conference
Trump skipped the traditional end-of-trip news conference to avoid facing questions about a host of problems he faces upon his return to Washington later on Saturday.
His May 9 firing of former FBI Director James Comey has raised concerns about whether he was trying to squelch a federal probe into his campaign's ties with Russia last year.
The questions have been intensified in the wake of disclosures on Friday that a senior adviser, Jared Kushner, the husband of Trump's daughter Ivanka, had contacts with the Russians in December about opening a secret back channel of communications with Moscow.
Trump used his trip to promote "America First" policies, promoting a $110 billion arms deal with Saudi Arabia and telling G7 allies that the US needs a more level playing field on trade.
His body language on the trip demonstrated his typically brash behavior, demanding that NATO allies pay more for their defence.
Trump's pushing aside of the prime minister of Montenegro to get in place for a family photo generated headlines across Europe.
Melania's flicking away her husband's hand twice also raised eyebrows during the trip.
