BAGHDAD (AP) — An Iranian exile group representing residents of a refugee camp outside Baghdad is alleging that one of its members has died after Iraqi authorities prevented him from being hospitalized.

The Paris-based National Council of Resistance of Iran said on Monday that Behrooz Rahimian died the previous day of cardiac arrest.

The group says he was rushed to a Baghdad emergency room with chest pain in late November, but accuses Iraqi authorities of intimidating doctors and refusing to allow him to remain there.

Members of the NCRI’s Mujahedeen-e-Khalq wing are living in a refugee camp outside Baghdad while the United Nations tries to resettle them abroad.

Iraqi Human Rights Minister Mohammed Shiyaa al-Sudani says he will launch an investigation into the death.
