Bulgarian authorities are focusing now on investigating the bombing and assisting international investigators who are probing the incident. Bulgarian Interior Minister Tsvetan Tsvetanov, who is in charge of the investigation, spends his time denying rumors spreading in the international media.
"In the last 48 hours we have gathered a lot of information that could bring progress to the investigation," Tsvetanov told reporters on Friday. "Experts are gathering the information and we are sharing it with all relevent parties," noting also the strong cooperation between Bulgaria and Israel.
Tsvetanov said the identity of the terrorist is still unclear, despite media reports that have made claims regarding the suicide bomber's name. "(The terrorist) was not in Guantanamo and there is no proof that he was sent by Hezbollah," Tsvetanov said, adding that caution should be taken when dealing with any information not approved by Bulgaria's Interior Ministry.
DNA samples taken from the terrorist's body were sent to U.S. intelligence agencies, but, as yet, no match has been found with any former Guantanamo detainees. Information was also sent to Interpol and was distributed to police forces around the world. Until now, no states have been able to identify the terrorist.
