Up to four people have reportedly been killed during an attempted mass break-inby migrants into the Spanish enclave of Ceuta in North Africa.Authorities say the victims were crushed to death as hundreds tried to cross the border from Morocco. Up to forty others were injured. Spanish officials have denied reports that police opened fire on the crowd. Earlier this week, African migrants were filmed trying to break through border fences around nearby Melilla. The activity resulted in almost 30 injuries as around 500 people used makeshift ladders to scale three-metre-high security fences. Many asylum-seekers are desperate to enter into Europe and this is one way. Police have logged 12,000 attempts to enter Melilla this year alone. Once over the fences almost all can claim asylum, although fewer than 10 percent of these applications are successful. The issue will top the agenda in talks in Seville today between the leaders of Spain and Morocco. Prime Minister Jose Luis Rodriguez Zapatero and his Moroccan counterpart, Driss Jettou, are only too aware that the close proximity of their countries is throwing up particular problems.
