Your morning briefing: What you should know for Tuesday, September 17

Donald Trump has warned that it is "looking like" Iran was responsible for the attacks on key oil installations in Saudi Arabia.

The president said the US is not looking at retaliatory options until he has "definitive proof" that the Middle Eastern country was behind the attacks.

Secretary of state Mike Pompeo also said "emerging information indicates that responsibility lies with Iran".

Iran has denied involvement, though it comes amid heightened tensions over Tehran's unravelling nuclear deal with world powers.

The US pulled out of the deal last year.

Tory MPs have criticised Luxembourg leader Xavier Bettel after he took aim at Boris Johnson at what would have been a joint conference.

The small European country’s Prime Minister angered many Conservatives after going ahead with his address alongside an empty podium yesterday.

Amid chaotic scenes outside Luxembourg's Ministry of State, Mr Johnson walked out complaining a noisy anti-Brexit demonstration made it impossible to go ahead.

To cheers from the crowd, Mr Bettel then mounted an emotional onslaught, complaining the future of citizens across the EU was being held hostage for "party political gains".

Even some pro-EU MPs supported Mr Johnson's decision to walk out. Sir Nicholas Soames, one of 21 MPs to have the Conservative whip removed by Mr Johnson for rebelling over Brexit, accused Mr Bettel of "unhelpful grandstanding".

A stately home has been raided by a gang of sledgehammer-wielding burglars who stole "priceless" jewellery King Edward VII had given to his mistress.

The thieves forced their way into the exhibition area of Sudeley Castle in Gloucestershire and stole serval valuable artefacts during the early hours of September 8.

Gloucestershire Police said last night that the four burglars were captured on CCTV approaching the property with a chair, sledgehammer and large garden or builder's bag.

Millions of people have been left in dark as a blackout hit at least four Central American countries.

Honduras was the hardest hit by the electrical grid failure, with all its territory and more than nine million inhabitants affected.

Nicaragua, El Salvador and Guatemala have also suffered partial outages.

The four nations plus Costa Rica and Panama have shared a linked electrical network since the late 1980s.

Ovie Soko has finally broken his silence on the rumours he and Love Island co-star India Reynolds have broken up.

The Love Island finalist and his girlfriend were faced with speculation last week that their romance had ended.

Rumours swirled along with claims the model had cheated on the basketball player with her footballer ex.

Speaking at the launch of his new ASOS collection, Ovie shut down the cheating rumours.

"Me and India are happy. I think that's definitely the most important thing. We're very happy,” he said.
