At least 23 migrants who died last month in a mass attempt to enter the Spanish enclave of Melilla from Morocco likely "suffocated", Morocco's state-backed CNDH rights group said on Wednesday.
The death toll after around 2,000 people, many from Sudan, stormed the frontier on June 24 was the worst in years of attempted migrant crossings into Spain's Ceuta and Melilla enclaves, which have two of the EU's only land borders with Africa.
