The latest development in yesterday's Bulgarian bus bomb explosion, is the identification of the alleged bomber. According to Times of Israel he is Mehdi Ghezali, "reportedly a Swedish citizen, with Algerian and Finnish origins. He had been held at the US’s Guantanamo Bay detainment camp on Cuba from 2002 to 2004, having previously studied at a Muslim religious school and mosque in Britain, and traveled to Saudi Arabia, Afghanistan, and Pakistan. He was also reportedly among 12 foreigners captured trying to cross into Afghanistan in 2009."

There's more:

Interior Minister Tsvetan Tsvetanov told Sofia that DNA tests were being run to determine the identity of the Caucasian man, who the minister described as casually dressed with nothing suspicious about his appearance to set him apart from the crowd of people at the airport.

Sofia also reported that the Bulgarian Interior Ministry managed to recover the fingerprints of the bomber, which they submitted to the FBI in the United States and the international police organization Interpol. The FBI and CIA joined Israeli and Bulgarian officials in investigating the attack.

What is curious is that this is not the first time Mehdi has made headline news. Below is a lengthy exposition on the Swede from 2009 via the Weekly Standard:

With a black baseball cap pulled tight over a mop of stringy long hair and a patchy, close-cropped beard, Mehdi-Muhammed Ghezali looked more like a Metallica roadie than a disciple of Ayman al-Zawahiri. He addressed the scrum of reporters in a clipped, heavily accented Swedish and accused the American government of wrongly detaining him for three years and "physically and mentally" torturing him. A book about his experiences was in the works; a documentary crew, cobbling together a film about American human rights abuses, had requested an audience; and his legal team was plotting a lawsuit against Donald Rumsfeld. It was 2004, and Ghezali was a free man.

In late 2001, Ghezali, a Swedish national, had been detained during the battle at Tora Bora, Afghanistan, handed over to the American military, and sent to the detention facility at Guantánamo Bay. According to his lawyers, he was simply in the wrong place at the wrong time. Although he spoke none of the local languages, Ghezali told his captors, in the midst of the Taliban's retreat into the mountainous hinterlands of Afghanistan, he had crossed that country's border with Pakistan to study Islam.

After an intense lobbying effort by Swedish prime minister Göran Persson--and a vague promise that the country's intelligence services would keep a watchful eye on him--Ghezali was delivered to Sweden (on the government's private Gulfstream jet). The Swedish daily Dagens Nyheter noted that Ghezali had achieved "rock star status" upon returning to his homeland, a native victim of America's rapacious imperialism. And after two-plus years in isolation, the emotionally fragile former prisoner would be happy to discover "that a majority of Swedes were glad that he was home."

That his story was threaded with head-scratching omissions and inexplicable gaps in chronology--the years in Cuba were, apparently, not enough time to concoct a consistent narrative--seemed to have little effect on his credibility. To his supporters, he was merely a bit player in a larger morality play. But even his most credulous supporters winced when, during a press conference in his hometown of Örebro, Ghezali offered the following opinion of Osama bin Laden: "I don't know him as a person and therefore can't pass judgment on him. I don't believe what the Americans say about him."

Sweden's justice minister ruled out prosecuting Ghezali, and the story faded from the public consciousness. But in a country with a significant Muslim minority, it was perhaps inevitable that the foreign ministry would find itself in a similar situation again.

In 2007, the Swedish government interceded on behalf of 17-year-old Safia Benaouda, a Stockholm native and convert to Islam, after she was arrested and jailed by the Ethiopian military, then battling Somali Islamists. Ethiopian officials told Sweden's foreign minister, Carl Bildt, that Benaouda had fled Somalia after the defeat of the Islamic Courts Union, on whose behalf she was accused of waging jihad, and had been detained with other fighters after crossing the border into Kenya.

According to the Stockholm-based newspaper Aftonbladet, Swedish diplomats engaged in "discreet meetings with the Pentagon, tribal leaders, and African government officials" to secure her release. Benaouda's mother, chairman of the Muslim Council of Sweden, wrote that her daughter was questioned by members of the CIA and beaten by guards--accusations amplified by the Associated Press. After her release, Benaouda went further, claiming that she was tortured in custody, a measure "planned and orchestrated by the Americans or other western interrogators." The claim ensured her permanent victim status in Sweden.

The cases of Ghezali and Benaouda--frequently invoked in the Swedish media as examples of America's tyrannical war on terror--were unrelated. There was no indication that the two had ever met or that they belonged to the same Scandinavian cell of Islamic militants. But the two innocents abroad, curious students of fundamentalist Islam, would soon find each other.

According to reports in the Swedish media, Ghezali and Benaouda were arrested last week in Pakistan--together, travelling with a multinational group of extremists--having crossed the border from Iran on their way to the al Qaeda stronghold of Waziristan. Pakistani sources claim that the group was carrying $50,000 in cash, maps indicating Western embassies, and--every religion student's best friend--an explosives belt. One of the suspects, according to a report in the Swedish newspaper Expressen, chewed up the SIM card of his cell phone before he was taken into custody.
