Some 500 African migrants charged the razor-wire border at Spain's north African enclave of Melilla on Wednesday, and many of the 100 who got through were injured, police said. It was the latest in a string of assaults in recent days at the crossings from Morocco to Melilla and Spain's other enclave Ceuta, the rich European Union's only land border with Africa, Reuters reproted. Five died last week in a similar attempt to use force of numbers to reach Ceuta; news reports said all were shot but it is still not clear by whom.
