[ISS] Until early 2018, violent extremism in West Africa had been largely confined to the Sahel region. Since then fears of a spillover into neighbouring coastal states, including Togo, have been rising. The risk to Togo became apparent on 15 February 2019 when a mobile customs unit was attacked in the Burkinabe town of Nohao, which borders Togo's Savanes region. Three customs officers and a Spanish priest were killed.
