The Moroccan navy has opened fire on a motorboat carrying migrants in Moroccan waters, killing a 22-year-old Moroccan woman and injuring three other people.
One of them has had his arm amputated and is in hospital in Rabat.
The Moroccan authorities said the Spanish skipper of the migrant boat refused to stop, adding that his passengers were lying flat and could not be seen from the naval vessel.
The International Organization for Migration says more than 38,000 migrants have reached Spain by land or sea this year, twice as many as last year.
