A human rights group is calling on Iraqi authorities to probe the killing of a journalist who criticized the government and helped organize pro-reform protests.
Hadi al-Mehdi, 30, was shot Thursday by gunmen using silenced pistols in his Baghdad home.
Friday's statement from New York-based Human Rights Watch said al-Mahdi had informed his friends of death threats he had received recently from unknown people.
Deputy Middle East Director Joe Stork said journalism in Iraq remains a deadly profession and Iraqis "who publicly express their views still do so at great peril."
Al-Mehdihad a weekly radio program in which he called on the government to provide better services, and he used Facebook to organize demonstrations every Friday in Baghdad.
