Eritrean by birth, Mr Isaak was forced to flee his native country in 1987 and arrived in Sweden as a beleaguered refugee during Eritrea’s bloody war for liberation. He became a Swedish citizen in 1992 after working for years as a cleaner, and he later returned to Eritrea when the country finally gained independence in 1996. Eager to develop the country’s independent press, Mr Isaak co-founded the country’s first independent newspaper, Setit, which would rise to national prominence as a professional paper and gain a reputation for investigative reporting which often focused on abuse of power by the government.

In May of 2001, a group of 15 cabinet members (prominent reformist politicians later dubbed the G-15), published an open letter to the government demanding democratic reform, and a thorough investigation of the events leading up to Eritrea’s recurring war with Ethiopia. The letter was published by the free press, most notably by Mr Isaak’s paper, Setit, which also went on to publish a series of similar open letters to president Isayas Afeworki demanding sweeping democratic reforms. The government acted in swift retaliation following the published demands of G-15, and by September, had effectively suspended all civil liberties in Eritrea.

On 23 September, all private press outlets in the country were officially shut down, and 11 of the G-15 politicians were arrested, along with Dawit Isaak and 13 other newspaper owners, editors and journalists. To date, none have been formally charged or tried, and Mr Isaak and the other journalists and politicians imprisoned with him have all been branded as traitors, accused of receiving financial aid from abroad, an act of criminal treason according to Eritrean press laws. According to reports, four of the journalists that were detained in 2001 have since died in prison.

In 2001, Sweden’s then honorary consul in Eritrea, Lis Truelsen, managed to get a glimpse of Mr Isaak through the prison bars and exchange a few words with him. The government of Sweden and the Swedish media community have undertaken numerous efforts to advocate for Mr Isaak’s release, without any success, as the Eritrean government has made it clear that his status as a dual citizen of Sweden is of little consequence. This position was reflected in public statements made in May 2009 by the country’s president, and in which he announced: "To me, Sweden is irrelevant. The Swedish government has nothing to do with us."

On 13 December 2008, it was reported that Mr Isaak had been moved to a maximum-security prison in Embatkala, along with 112 other political prisoners. The move was allegedly by the explicit order of the President, and the Embatkala prison is reportedly one of the harshest prison environments in the country. Several weeks later, on 11 January 2009, reports surfaced that Mr Isaak had been transferred to a military hospital, and despite government assurances that he is receiving all necessary medical treatment, the details of his actual whereabouts remain sketchy.

A controversial Swedish interview with Eritrean president Issayas Afwerki drew the attention of human rights watchdog organisations when he declared unceremoniously that there were no plans to release Mr Isaak, nor to conduct a trial in which the journalist would be formally charged. The interview, which was broadcast on 26 May 2009, stirred international controversy when the Eritrean president dismissed the issue of Mr Isaak’s imprisonment altogether, stating without qualm: "We will not have any trial and we will not free him. We know how to handle his kind."
