Several of Al-Hayat's other offices have been singled out over the past weeks. Two such bombs arrived at the paper's Riyadh bureau on January 4 and 11, while five went to the Al-Hayat office in Washington DC. All the bombs were defused, except for two which critically injured two employees at the paper's London headquarters on January 13. The London explosion prompted Rashida Dergham, the paper's UN correspondent, to immediately alert the UN secretary to screen her mail. Two bombs were detected and defused the same morning while two more were found and defused later in the day. Mail delivery to the UN, which receives approximately 15,000 letters a day, was suspended by the US postal service for a day after the bombs were received. Al-Hayat has a circulation of roughly 200,000 but is considered one of the most avidly read newspapers in West Asia. As Dergham points out, the paper's editorial policy has been consistent in that it has criticised almost everyone in West Asia uniformly, without singling out any one organisation. And journalists at the paper remain determined "to pursue their journalistic objectives with all their might, objectively and humbly". Al-Hayat has been the target of such attacks right from its early days. In 1966, Kamel Mrowa, the paper's founder, was shot dead in his Beirut office, as he was adding the final touches to the next day's edition. Supporters of the then Egyptian president Gamal Abdel Nasser were felt to have been behind the killing, spurred by the paper's criticism of the Arab nationalist movement. "My father died with two phones in his hands and his pen on his desk, because he refused to back down or shut up," Hayat Mrowa Palumbo, Mrowa's daughter, now a US resident, told New York Times.
