"His murder has prompted a global reassessment of the Saudi crown prince and a really long overdue look at the devastating war in Yemen."The two Reuters journalists have been imprisoned for nearly a year in Myanmar after investigating a massacre of Rohingya Muslims.WATCH: Khashoggi killing: Crown Prince Muhammad Bin Salman sent 11 messages to top aid before and after Khashoggi's deathIn the hours before and after journalist Jamal Khashoggi was killed, Saudi Crown Prince Mohammed bin Salman and a senior aide who allegedly oversaw the assassination exchanged multiple messages. Ressa is an award-winning Philippine journalist who, along with the online news service she heads, Rappler, has been sued for tax evasion.Her website has been critical of the government of Philippine President Rodrigo Duterte, and she says the charges are politically motivated.She told Al Jazeera from Manila the nomination showed "how difficult it is to be a journalist"."This year we can't get away from the impunity and the brutal killing of Khashoggi, the jailing of the Reuters journalists and the challenges we face here [in the Philippines], what's happening in the United states," she said."Journalists are under attack both online and in the real world and these real world dangers are something we have to fight to just be able to do our jobs."In her own case, she said "the law had been weaponised" against Rappler. She vowed to keep on fighting in court.Time has made the designation every year since 1927. The magazine says the Person of the Year title is not necessarily an honour or award, but representative of the influence the person - or idea - has had on the news within the past year - for better or worse.
