Burkina faso buhari commends ecowas leaders on peace efforts

I think there may be a few issues with the sentence you provided. Here's a breakdown:

• "Burkina Faso" is a country in West Africa, but it's not clear what it has to do with the rest of the sentence.
• "Buhari" is the name of the President of Nigeria, Muhammadu Buhari. It's unlikely that he would be commending ECOWAS leaders on peace efforts in Burkina Faso, as that would be a different country.
• "ECOWAS" is the Economic Community of West African States, a regional organization that aims to promote economic integration and cooperation among its member states.

Here's a possible rephrased sentence:

"Nigerian President Muhammadu Buhari has commended ECOWAS leaders for their efforts to promote peace and stability in the region."

Or, if you meant to say that the President of Burkina Faso was commending ECOWAS leaders, the sentence would be:

"The President of Burkina Faso has commended ECOWAS leaders for their efforts to promote peace and stability in the region."

Let me know if you have any further questions or if there's anything else I can help with!
