West African leaders will discuss on Sunday how to respond to a coup in Mali, gathering in the Ghanaian capital Accra for a summit to be attended by Assimi Goita, who was named interim Malian president after leading the takeover last week.

The revolt has prompted sanctions warnings from foreign powers, which fear it will derail a promised transition back to democracy following another coup last August led by Goita, an army colonel.

Goita has flown to Accra for the summit, according to his administration. The talks are scheduled to start at 1400 GMT.

ECOWAS closed borders with landlocked Mali and halted financial transactions in response to last year’s coup. The sanctions led to a 30% slump in imports before they were lifted last October.
