An international military intervention is needed to end unrest in Libya, where the Islamic State group is gaining a foothold, Spanish Defense Minister Pedro Morenes said in an interview published Saturday.

"We went to Afghanistan to stop all of that from coming here, we are in Iraq, Mali or Somalia with the same objective. And now we have it nearby. Something may need to be done," he told the top-selling Spanish daily El Pais when asked if there would be a military intervention in Libya.

Spain's prime minister lashed out Friday against the rapprochement between the main opposition Socialists and new anti-austerity party Podemos to try to oust his conservative government in several areas, calling it a "tremendous mistake."

The ruling Popular Party suffered heavy losses during regional and local elections on May 24 while Podemos made strong gains, making them kingmakers in post-electoral government negotiations ahead of a general election due in November.

An analysis of the black boxes of the A400M plane which crashed in Spain has revealed that three of the aircraft's four engines failed before it ploughed into a field killing four in May, Airbus said Wednesday.

Globe-trotting U.S. diplomat John Kerry on Tuesday underwent successful surgery to mend a broken leg, and his doctor hopes to get him up and walking within 24 hours.

Two major newspapers are now counting the number of people killed by police in the United States, as the debate over the use of deadly force by officers, especially against minorities, rages on.

Former leaders from Spain and Latin America called Monday on Venezuela's President Nicolas Maduro to free political prisoners, "respect fundamental rights and liberties" and create a climate for political dialogue.

A Spanish High Court judge said Thursday he has agreed to hear a lawsuit against Nigerian Islamist militant group Boko Haram and its leader Abubakar Shekau for crimes against humanity and terrorism.

Judge Fernando Andreu ruled he was competent to handle the case under the principle of universal jurisdiction -- which allows courts to try certain atrocities committed in other countries -- because the case concerns a Spanish nun who is a victim of the group.

By voting in local elections for upstart parties that vow to fight corruption and an economic downturn, Spanish voters will force their politicians to learn to form coalitions, analysts say.

Prime Minister Mariano Rajoy's conservative Popular Party suffered huge losses in Sunday's regional and local polls ahead of a year-end general election and the main opposition Socialist party failed to capitalize on its adversary's weakness.

Spain faced a changed political landscape Monday after the "Indignado" protest movement gave the ruling conservative rivals a battering in local elections, topping the vote in Barcelona and shattering the governing party's majority in Madrid.

In a dramatic shakeup of Spanish politics, an upstart group backed by the anti-austerity protest party Podemos could now govern in the capital, a longtime conservative stronghold.
