ACCRA (Reuters) - West Africa's main regional bloc will close borders with Mali and impose sweeping economic sanctions in response to delays holding promised elections after a 2020 military coup, the president of the bloc's commission said on Sunday.

       The announcement followed an extraordinary summit of the leaders of the 15-member Economic Community of West African States (ECOWAS) in the Ghanaian capital Accra.
