A Bad Bunny concert ended in chaos after golf ball-sized hailstones fell from the sky and left fans with head injuries.

The Saturday evening show in Milan's open-air La Maura Hippodrome was forced to shut down amid the poor weather, which has hammered the continent over the last few weeks.

Footage from the concert showed the extent of the injuries suffered by some of the nearly 80,000 fans in attendance of the gig, the second and final of two Milan dates for Bad Bunny's Debí Tirar Más Fotos world tour.

One clip posted to TikTok showed a woman pulling bloodied rags from a man's head, after he was apparently hit by the hailstones.

Another clip showed a group of women all walking in formation under a collection of thick coats that were put up to stop the hail from hitting them.

Many were seen in videos posted online putting up umbrellas, or spreading their coats above their heads.

The wind, lightning, rain and hail forced Bad Bunny, whose real name is Benito Antonio Martínez Ocasio, to cancel his set by the seventh song.

Loudspeakers at the venue urged the audience to leave as soon as possible.

The evacuation began at around 9.30pm local time, and ended at 10.20pm that evening, event officials said.

After consulting with local police, LiveNation Italy boss Roberto De Luca said the concert would be fully cancelled, not rescheduled, and that fans would be refunded for the tickets.

He said: 'We did everything possible to best address the emergency that affected the 78,000 spectators at the Bad Bunny concert.

'An emergency, it must be said, that I have never faced before in 45 years of working in this field.'

De Luca added: 'We are here to thank the security personnel who played a decisive role in ensuring the safety of the crowd, and we extend our gratitude to the audience who remained calm and cooperative during the emergency.'

Elsewhere in Europe, hundreds of people have been forced to flee their homes as major wildfires continue to rage across southern Europe.

Spain is battling multiple blazes while popular holiday destinations in France remain on high alert ahead of another intense heatwave expected to push temperatures close to 45C.

Fire crews in Spain are continuing to tackle a major wildfire north of Madrid that has burned around 13,000 hectares (32,000 acres) and prompted the evacuation of about 700 residents.

Prime Minister Pedro Sánchez said his government was closely monitoring the situation and praised emergency crews for their relentless efforts to contain the blaze and protect nearby communities.

Around 300 firefighters, backed by 26 water-bombing aircraft, have been deployed to the fire, which ignited on Thursday in the province of Guadalajara during a spell of extreme heat.

Regional officials have described the blaze as particularly difficult to contain because of the rugged, forested terrain surrounding the Sierra Norte Natural Park, an area home to endangered wildlife including wolves, golden eagles and rare butterfly species.

Elsewhere in Spain, firefighters have gained ground on a separate wildfire near Zaragoza in the north-eastern region of Aragon, where around 1,000 residents were evacuated after flames swept through the countryside.

Authorities say the blaze has burned approximately 14,400 hectares after improved weather conditions slowed its advance.

No deaths or injuries have been reported, while emergency officials are assessing when evacuated residents can safely return home.

Spain's State Meteorological Agency (Aemet) has warned the country is about to enter its third heatwave of the summer, with temperatures forecast to climb steadily before peaking later this week.

Some parts of southeastern Spain could approach or even exceed 45C, dramatically increasing the risk of new wildfires as vegetation dries out further.

The warnings come after Spain suffered one of its deadliest wildfires in recent years earlier this month, when 13 people were killed in a blaze in Almería that destroyed around 7,000 hectares.

In neighbouring France, thousands of people have already been forced to evacuate as a series of fast-moving wildfires swept through the country's Mediterranean regions following last month's record-breaking heatwave.

One of the largest fires erupted near Trévillach in the foothills of the French Pyrenees close to the Spanish border, scorching more than 4,600 hectares and forcing more than 10,000 people to leave over a dozen villages.

French Interior Minister Laurent Nunez warned that worsening weather conditions and powerful winds threatened to reignite the fire's spread, while residents described flames racing towards homes in a matter of minutes.

'It came within 300 metres of the houses. We were stunned by how quickly it spread,' one resident told local media.

The wildfire also disrupted the Tour de France, with organisers urging spectators to avoid the final section of one stage so emergency vehicles could move freely through the affected area.
