DODOMA, Tanzania—Police in Tanzania say three people, including two police officers, have been shot dead in a confrontation near the French Embassy in Dar es Salaam. Inspector general of police Simon Sirro told reporters that the armed man was a foreigner and police believe he was from Somalia. Sirro also warned that the attack could be linked to the jihadist insurgency in neighboring Mozambique. The U.S. Embassy in a security alert warned citizens to avoid the area. The confrontation occurred shortly after President Samia Suluhu Hassan addressed security officials in another part of the city, Tanzania’s commercial hub.
