DAKAR, Senegal — Senegal is hosting Gambia’s President-elect Adama Barrow until his Jan. 19 inauguration, as the small West African country’s longtime leader refuses to step down peacefully despite mediation efforts and calls from regional and international leaders.

President Yahya Jammeh initially conceded to Barrow after losing elections on Dec. 1 but changed his mind a week later, saying the vote was invalid, citing irregularities.

His party has submitted a petition to the Supreme Court against the results, but there are not enough judges currently presiding to hear the case.
