Spanish Prime Minister Mariano Rajoy scrambled Wednesday to contain the fallout of a new graft scandal involving members of his conservative Popular Party which has outraged voters ahead of next year's general election.

Rajoy apologized in the name of his party "for having put people in positions of responsibility who were not fit for them and who apparently abused their positions" during a debate in parliament on Tuesday evening.

Some 350 African migrants tried to storm a fence from Morocco into Spanish territory on Wednesday, authorities said, the latest in a wave of desperate arrivals at Europe's southern border.

Just three of the migrants who charged towards the seven-meter (23-foot) fence in separate locations at dawn made it into the territory of Melilla, the Spanish government delegation there said in a statement.

The U.N. on Tuesday warned Spain over plans to instantly deport migrants who clamber over the border fence into its north African territories, saying Madrid could end up breaking international law.

"UNHCR is concerned over a proposal by Spain to legalize automatic returns of people trying to cross border fences into its enclaves of Ceuta and Melilla," said the U.N. refugee agency's spokesman William Spindler.

Iran's Foreign Minister Mohammad Javad Zarif will visit Spain next week before heading to China for the fourth regional conference on Afghanistan, an official said Wednesday.

Health Minister Wael Abou Faour said Wednesday that flights arriving from countries where there is an Ebola outbreak would land in one terminal as he announced further measures to stop the virus from reaching Lebanon.

Migrants are scrambling to reach Spain's north African territory Melilla at double the rate of last year, an official said Tuesday, speaking days after evidence of abuse by border guards sparked outrage.

The head of the Spanish government delegation in the territory Abdelmalik El Barkani said the number of attempts by desperate migrants to scale the seven-meter (23-foot), triple layer fence separating Melilla from Morocco had surged so far in 2014.

Spain's government vowed Monday that it would smash the Basque separatist group ETA after claiming that it was still "alive" three years after it ended its violence.

"ETA is not operational but it is alive," Interior Minister Jorge Fernandez Diaz told reporters in Vitoria, the capital of Spain's Basque region.

About 60 Africans scrambled over a border fence from Morocco into Spanish territory Monday, as a U.N. official urged Spain to protect migrants' rights following evidence of police abuse.

It was the latest in a string of attempts by desperate Africans trying to reach European soil by scaling the seven-meter (23-foot), triple-layer fence into the Spanish territory of Melilla, raising pressure on Spain's government.
