[Al Arabiya Latest] A relative of Iranian opposition leader Mir Hossein Mousavi said his nephew's body was removed from hospital without the family's permission, a day after he was shot dead in clashes during anti-government protests, which state TV said killed 15 people.The body of Seyed Ali Mousavi, the nephew of Iran's opposition leader killed in Tehran protests, has been transferred from the hospital to an unknown location, his brother told a website on Monday.
"My brother's body was taken away from the hospital and we cannot find it," Seyed Reza Mousavi told Parlemannews, the website run by the reformist minority faction in parliament.
"Nobody accepts responsibility for taking away the body ... We cannot have a funeral before we find the body."
The 35-year-old nephew of Mir Hossein Mousavi was shot dead in Tehran's Sunday protests which turned into the bloodiest showdown between opposition protesters and security forces in months.
Tehran police said they were investigating the death.
"The killing of Mousavi's nephew in Ashura incidents is being investigated and the result will be announced soon," Tehran police chief Azizollah Rajabzadeh told ILNA news agency on Monday.
Jaras said opposition politician Ebrahim Yazdi, leader of the banned Freedom Movement and foreign minister in Iran's first government after the 1979 Islamic revolution that overthrew the U.S.-backed shah, was detained early on Monday at his home.
Authorities also arrested aides to reformist ex-president Mohammad Khatami and Mousavi, another website reported.
Khatami aides "Morteza Haji and (Hasan) Rasooli were arrested," Parlemannews said. The two men run Khatami's non-governmental Baran organisation.
"Mousavi advisors Alireza Beheshti, (Ghorban) Behzadian-Nejad and (Mohammad) Bagherian were also arrested in the morning," it added.
