Morocco's ambassador to Spain has threatened more reprisals against Madrid over its decision to allow a Western Sahara independence leader to be treated in a Spanish hospital.
Karima Benyaich said elements in the Spanish government did not take the interests of Morocco into account, despite assurances from Madrid that Spain wants to move on from the crisis that led to thousands of migrants flooding into Spain's North African enclave, Ceuta, last week.
Morocco is suspected of opening the borders to the would-be migrants.
Analysts have suggested the threatened further reprisals could mean Rabat will not cooperate in anti-terrorist operations.
Thursday a Spanish court jailed three men of Moroccan origin for up to 53 years for playing a part in the 2017 Barcelona terrorist attacks which killed 16 people.
Polisario Front leader Brahim Ghali will appear before a Spanish court on June 1 to answer torture charges brought by a Western Sahara dissident group. The front represents the Sahrawi people who are native to the Western Sahara territory.
