Spain asked to explain deaths at Moroccan border crossing

Doubt cast on official version of events after deadly crush at border fence in which at least 23 died

The Spanish government is facing growing calls to explain how at least 23 people died during a mass storming of the border fence between Morocco and Spain's north African enclave of Melilla almost five months ago.

MPs who visited the border on a fact-finding trip have appeared to corroborate reports - first aired in a BBC Africa Eye investigation broadcast last week - that dead bodies were dragged out of a Spanish-controlled area by Moroccan police.
