The first trailer for the third Avengers film has been released, hinting it will bring to an end the biggest superhero franchise in the world.

In a little over two minutes, Marvel Studios has left fans hoping for the best but expecting the worse, as rumours emerge that its most profitable franchise could be drawing to a close.

Nearly a decade after the Marvel Cinematic Universe was born, studio boss Kevin Feige hinted that this was it: the end.

In an interview with Vanity Fair on Tuesday, Feige refused to share many details, but said Avengers: Infinity War will "bring things you've never seen in superhero films: a finale".

The Marvel head explained how the upcoming assemble film would act as a passage from the old franchise to a new one, meaning the MCU will live on.

The US has warned the North Korean regime that its country would be "utterly destroyed" if war were to break out.

Hours after the isolated state's latest ballistic missile test, the US ambassador to the UN urged all countries to cut diplomatic and trade ties with Pyongyang.

At an emergency meeting of the UN Security Council, Nikki Haley said: "We have never sought war with North Korea, and still today we do not seek it.

"If war does come, it will be because of continued acts of aggression like we witnessed yesterday.

"And if war comes, make no mistake, the North Korean regime will be utterly destroyed."

The Prime Minister believes investment and jobs will help tackle the "root causes of terrorism" in the Middle East as she makes a new commitment to Jordan.

On a visit to the country, Theresa May will vow new long-term financial backing to help Jordan transform its economy.

The UK will initially provide £94.5m to improve education, create jobs, and "boost Jordan's long-term economic resilience".

Speaking in the capital Amman, the Prime Minister called on the rest of the international community to contribute.

"Jordan's stability is crucial to our interests in the Middle East and we are committed to helping them create jobs for all Jordanians," she said.

"I call on other countries to join us in this transformative effort so Jordan can continue to deliver vital support for the Syria crisis and remain a beacon of hope in the Middle East."

Jordan borders conflict zones in Syria and Iraq and currently hosts 1.3 million Syrians, half of them registered as refugees.

An Australian watchdog has banned the use of controversial vaginal mesh implants for prolapse after a review found "the benefits do not outweigh the risks these products pose to patients".

The Therapeutic Goods Administration has decided to remove the use of mesh products in the treatment of pelvic organ prolapse and single incision mini-slings which is used to treat urinary incontinence.

This move follows the news that NICE, the health watchdog in the UK, will recommend that mesh should be banned as a routine treatment for prolapse, a condition when organs such as the vagina, uterus or bowel fall down or slip out of place.

The draft guidance, seen by Sky News and due to be published next month, states that mesh implants for prolapse should now only be used for research purposes.

It does not affect the use of mesh for incontinence which accounts for the majority of operations.

Kath Sansom, founder of the campaign group Sling the Mesh, has welcomed the latest developments.
