ANKARA, Turkey -- Iran's military prosecutor-general Ali Qoddousi was fatally wounded today when a powerful explosion ripped through his office in downtown Tehran.
It was the second major bombing this week against high-ranking members of the Ayatollah Ruhollah Khomeini's Islamic regime.
Qoddousi was the clergyman reponsible for trying military personnel.
He was rushed to the hospital with leg injuries and underwent surgery but died soon after, a hospital spokesman said.
'Brother Qoddousi is martyred,' he said.
The spokesman gave no additional details.
Qoddousi was the chief instrument of Khomeini's crackdown on dissidents. Revolutionary courts under his command executed 659 political dissidents convicted of supporting ousted President Abolhassan Bani-Sadr.
Tehran radio monitored in Ankara said the device was planted in a library a floor below Qoddousi's office in the joint armed forces command headquarters.
In another development, Tehran Radio said Iran's police chief died today of injuries suffered last Sunday when a bomb exploded in the prime minister's office, killing President Mohammed Ali Rajai and Prime Minister Mohammed Java Bahonar.
The Tehran Radio report, monitored in Ankara, was the first news that police chief Col. Hushang Vahid Dastgerdi also was injured in last week's explosion.
'I was 20 meters (66 feet) from the building when the bomb went off and I saw the terrace of the second floor collapse,' Hojjatoleslam Reyshahri, the Islamic judge who heads the military courts, said in an interview with Pars following today's attack.
Reyshahri said Qoddousi's 'leg was burned and he was rushed to the hospital,' according to the Pars report, monitored in Ankara.
'The explosion appears to have been in the middle of the building,' a police spokesman reached by telephone said.
Other witnesses reached by telephone said security forces set up road blocks around the wrecked building. Ambulances were seen rushing to the military prosecutor's office in downtown Tehran, the witnesses said.
Iran's chief justice, Ayatollah Abdolkarim Mousavi-Ardebili, Friday empowered security forces to make mass arrests in the search for the those responsible for the bombing.
Chief government spokesman, Behzad Nabavi, said Thursday employees of the prime minister's office had been arrested and the Mojahidden Khalq guerrilla organization was the prime suspect in the investigation into the bombing.
