Bodyguards for Somalia’s auditor general shot dead a government minister in an apparent accident near the presidential palace in Mogadishu on Wednesday evening, police said.

Auditor general Nur Farah’s bodyguards opened fire on a car carrying Abbas Abdullahi Sheikh Siraji, the public works and reconstruction minister, near a checkpoint close to the palace, said police captain Mohamed Hussein.

Senior Somali security member Mohamed Hassan told the German news agency that the minister’s bodyguards had falsely identified Farah, who was travelling in a bulletproof vehicle, as a threat and there had been an exchange of gunfire.

Several of Siraji’s bodyguards were wounded in the incident, according to Hassan. Another minister who was in the car with Siraji survived.

The auditor general escaped unharmed.

Security concerns are high in Somalia’s capital, Mogadishu, as the al-Shabab armed group continues to target the palace, military facilities and hotels with suicide car bombings and other attack
