Spain suffers fresh floods as torrential rains strike

Floods trapped people in vehicles and homes in Spain on Sunday as torrential rain drenched the northeastern Catalonia region, a day after downpours unleashed travel chaos on the Mediterranean island of Ibiza.

Local media shared videos of roaring torrents of brown water tearing through streets and submerging vehicles.

National weather agency AEMET decreed the highest red alert in the province of Tarragona, warning of 180 millimetres of rain in 12 hours in the Ebro river delta.

Catalan fire service spokesman Oriol Corbella told reporters people had been caught by surprise, with people trapped "inside vehicles, in buildings, on ground floors".

The mayor of the town of Santa Barbara, Josep Lluis Gimeno, told regional television station 3Cat the situation was "very tense" as the night brought heavier deluges.

Local streams and ravines "are completely overflowing and have invaded the entire centre of the town, dragging everything there is, containers and cars", he said.

Spanish PM to attend signing ceremony in Egypt to mark end of Gaza war

Spain's Prime Minister Pedro Sánchez will travel to Egypt on Monday to attend the ceremony marking the signing of the end of the war in Gaza.

The event will also be attended by the President of the United States, Donald Trump.

Sánchez, who has been one of Europe's leading pro-Palestinian voices since the outbreak of the conflict, last week welcomed the agreement between Israel and Hamas, saying he hoped that "it is the beginning of a just and lasting peace."

"Now it is time for dialogue, to assist the civilian population and to look to the future. With hope, but also with justice and with memory so that the atrocities we have lived through are never repeated," Sánchez said.

Spain arrests 17 after clashes at fascist rally

Spanish police said they had arrested 17 people in the northern city of Vitoria on Sunday after fascist supporters of former dictator Francisco Franco clashed with counter-protesters.

The rare violence comes as the European country marks the 50th anniversary of the general's death and grapples with the divisive legacy of his iron-fisted 1939-1975 rule.

The Falange -- an organisation that sees itself as the successor to defunct fascist movements that helped bring Franco to power -- rallied on national day in the northern Basque Country, which has a historic separatist movement, to defend "the unity of Spain".

Dozens of demonstrators gathered in a central square in Vitoria making fascist salutes and brandishing red and gold Spanish flags before hooded counter-protesters burst onto the scene, footage on social media showed.

Police charged at the rival protesters who were striking each other with poles, flags and chairs and hurling flares, according to the images.

Basque police said they had arrested 17 people suspected of public disorder after "radical groups" faced off, threw objects and burned waste containers.

Around 20 officers suffered "light bruises" and medical staff treated the injured protesters at the scene, the police added in a statement.

Spain to have a second European AI factory in Galicia

Spain will have a second European artificial intelligence (AI) factory based in Santiago de Compostela, where the Galician Supercomputing Centre (Cesga) will be built, according to the Xunta de Galicia.

The centre, one of six new European artificial intelligence factories, will be spurred by an initial investment of €82 million.

The factory will focus on healthcare services under the name 1HealthAI and will acquire a new AI-specific supercomputer and an advanced supercomputing platform optimised for experimental AI.

Spain says Israel frees its last Gaza flotilla members

Israel has released the five remaining Spanish detainees from flotillas it blocked while they were carrying aid and pro-Palestinian activists to devastated Gaza, sources at Spain's foreign ministry said over the weekend.

Israel has this month intercepted in international waters two flotillas aiming to break its blockade of Gaza, where the United Nations has declared a famine after two years of brutal conflict.

Israel arrested the crews, with Swedish climate campaigner Greta Thunberg among the dozens of activists of various nationalities, sparking huge protests in Europe.

Israel has been releasing them over recent days, with Spanish foreign ministry sources saying: "The last five members of the flotilla held by Israel are now on their way to Spain."
