Former Greek Prime Minister Lucas Papademos was injured Thursday in central Athens, Greece, after a bomb detonated in his car, police said.
According to the U.K.'s Express, Papademos and his driver were "rushed to the hospital" after an explosive device detonated inside the vehicle. The source of the explosion was hidden inside an envelope. It was not immediately clear whether the car was moving at the time.
Police did not immediately say if the attack was terror-related.
The incident came just days after more than 20 people died in what British officials have since deemed a terror attack at an Ariana Grande concert in Manchester, England.
BBC News reported that Papademos, 69, suffered a non life-threatening leg injury. Two more people, whom the BBC reported to be banking officials, were also in the car and suffered injuries. although the extent of those injuries were not clear.
Nikos Pappas, Greece's media minister, responded to the incident on local TV.
"We are shocked. I wish to condemn this heinous act," Pappas said, according to Sky News.
Papademos served as Greece's prime minister from 2011-2012 — the pique of the country's debt crisis.
Before becoming prime minister, Papademos worked as vice president of the European Central Bank from 2002-2010.
