Three West African leaders are in Burkina Faso to push army leaders to honor their pledge to hand over power to a civilian transitional government.
Ghana's President John Mahama, Nigerian President Goodluck Jonathan and Senegalese President Macky Sall arrived in the capital, Ouagadougou, on Wednesday.
The presidents are expected to meet with Burkina Faso's interim leader, Lieutenant Colonel Isaac Zida, as well as leaders of the opposition.
The military took control Friday after president Blaise Compaore resigned and fled to neighboring Ivory Coast.
Ivorian President Alassane Ouattara said Tuesday that Mr. Compaore is in "good spirits" and can stay as long as he wants.
The military appointed Lieutenant Colonel Isaac Zida as an interim leader, and he has said several times he would quickly transfer power.
On Monday, the African Union warned that Burkina Faso faces possible sanctions unless a civilian government takes power within two weeks.
An attempt to extend his rule ended in failure last week when protesters burned parliament, hours before lawmakers were due to vote on a measure eliminating term limits.
