The police cordoned off the area where Nahed Hattar, a Jordanian writer, was fatally shot in Amman on Sunday. Ahmad Alameen/Agence France-Presse — Getty Images Relatives said Mr. Hattar received more than 100 death threats, many through Facebook and some by telephone. In one message they played for a reporter, a caller said if justice did not take place, he would kill Mr. Hattar by “tearing out his heart from his chest.” The family said it went to the governor to submit the death threats but no action was taken. “This happened despite the government knowing that Nahed is a prominent person, that he received hundreds of death threats,” said Saif Hattar, his cousin. After Mr. Hattar’s death on Sunday, a range of organizations in Jordan spoke out against the killing, including the Islamic Action Front, the political wing of the Muslim Brotherhood. “The murder of Hattar targets democracy and diversity in our society and aims to spread darkness and terrorism,” Nidal Mansour, the president of the Center for Defending Freedom of Journalists, said in a statement. “Even though we disagree with what Nahed says or writes, this is the time to stand united against terrorism and those who killed him. They want to instill fear and silence us.” At the family meeting hall in Amman, relatives consoled one another. His wife, Mrs. Kakish-Hattar, said she tried to convince Mr. Hattar to leave the country just two days earlier, but he refused. Mr. Hattar’s younger brother, Majed, 51, was with him when he was converted by Web2PDFConvert.com
