Updated at 1:29 p.m. ET: Former Guantanamo Bay detainee Mehdi Ghezali was named by Bulgarian media Thursday as the suspected suicide bomber who killed at least seven people and injured dozens on a bus full of Israeli tourists.
The Muslim Swede had been held at Guantanamo Bay in Cuba from 2002 to 2004, according to media reports picked up by The Times of Israel.
He previously studied at a Muslim religious school and mosque in Britain, and traveled to Saudi Arabia, Afghanistan, and Pakistan. He was released to Swedish custody in 2004, the Times reported. The Swedish government did not press charges, it said.
NBC News learned Ghezali was also reportedly among 12 foreigners captured trying to cross into Afghanistan from Pakistan in 2009. He was accused of conspiring with al-Qaida in North Waziristan and returned to Sweden.
A Department of Defense list obtained by NBC News includes a man of the same name, born in Stockholm, Sweden, on July 5, 1979, and identified as inmate No.166, being released from Guantanamo Bay on July 8, 2004.
If Ghezali is the same person, he would be one of more than 50 former Gitmo detainees who have returned to the fight after their transfer or release.
