G7 summit agrees on countering terrorism but not climate change
Leaders of the world's leading industrial nations, the G7, have agreed on new action to counter terrorism at a summit in Taormina, Sicily.
However, differences over climate change remain between US President Donald Trump and the others, said the host, Italian PM Paolo Gentiloni.
Mr Trump and UK Prime Minister Theresa May reaffirmed plans to boost trade, including a post-Brexit trade deal.
Mr Trump has welcomed the UK's vote to leave the European Union.
They are both attending their first G7 summit, as are Mr Gentiloni and French President Emmanuel Macron.
The G7 consists of Canada, France, Germany, Italy, Japan, the UK and the US, while the European Union (EU) also has representatives present.
What did they say about terrorism?
"We showed our united commitment and our determination to continue and to strengthen our fight against terrorism," said Mr Gentiloni.
The leaders signed a document saying more should be done by internet companies to identify and remove extremist material.
The leaders also voiced solidarity with the UK after Monday's bombing in Manchester in which 22 people, including children, were killed.
Why no deal on climate change?
Mr Gentiloni said the leaders had not managed to come to an agreement on climate change because the Trump administration was still considering its position.
President Trump has previously threatened to pull out of the Paris Climate Change Accord of 2015.
"The question of the Paris climate accord is still hanging," said Mr Gentiloni.
"We are sure that after an internal reflection, the United States will also want to commit to it," he added.
Was the trade news all good for May?
According to the French news agency AFP, President Macron "snubbed" the British prime minister when they held their first official talks on the sidelines of the summit.
Mrs May told him that the UK and the 27 EU member states should be discussing their future relationship at the same time as discussing the terms of the UK's withdrawal, a Downing Street spokesman said.
However, a source in the French delegation said Mr Macron had repeated the EU's position that the terms of the divorce must be agreed first.
Mrs May later told reporters she had had a "very good and productive discussion" with Mr Macron.
Was there any other progress on trade?
Mr Gentiloni said progress had been made but the wording of the final communique still needed to be worked out.
"But it seems to me the direct discussions today have produced common positions that we can work on," he added.
There has been concern that the US president might promote a protectionist agenda.
German weekly Der Spiegel quoted Mr Trump as saying in a meeting with European Commission President Jean-Claude Juncker on Thursday that Germans were "very bad" regarding car exports to the US.
During his election campaign last year, Mr Trump threatened customs duties in retaliation for Germany's trade surplus with the US, saying it owed "vast sums of money" to the US and Nato.
What did Trump and Abe decide?
The US president and Japanese Prime Minister Shinzo Abe discussed the nuclear and missile threat from North Korea.
They agreed to "enhance sanctions on North Korea, including by identifying and sanctioning entities that support North Korea's ballistic missile and nuclear programs", the White House said.
What else has happened in Trump's first foreign tour?
Addressing a Nato summit in Brussels on Thursday, Mr Trump insisted that all members of the alliance should contribute more financially on defence.
Nato states' contributions are voluntary and a target of spending 2% of GDP on defence is only a guideline, but the US is concerned that members are not paying enough.

The bloc later agreed that member states would report back annually on defence spending to Nato.
It also said it would take a bigger role in the campaign against IS militants, but France and Germany have insisted the move is mostly symbolic.
The G7 summit brings Mr Trump's first foreign tour as US president to a close. Earlier in the week, he said he was "more determined than ever" to pursue peace in the world after meeting Pope Francis at the Vatican.
Before that, he vowed to help Israelis and Palestinians achieve peace, as he ended the Middle East leg of his tour.
He began his foreign trip with a two-day stop in Saudi Arabia over the weekend, urging Muslim countries to take the lead in combating radicalisation.
