Costa Rican President Laura Fernández has dismissed Foreign Minister Manuel Tovar after he attended a US-led regional security summit with President Donald Trump in New York without informing her. Fernández said she should have represented the country at the "Shield of the Americas" gathering — a coalition of nations formed to combat drug trafficking and organised crime — which took place on the sidelines of the UN General Assembly. The government said Tovar's failure to notify her blocked her own participation and caused significant harm to Costa Rica's strategic interests; Trade Minister Indiana Trejos has been named acting foreign minister in his place.
