“The culprits behind the Attock district attack have been identified and efforts are underway to arrest them,” Radio Pakistan quoted Sanaullah as saying in a news conference in Lahore on Tuesday.
“The government will not rest till the culprits have been brought to justice,” he said.
He said the resolve of the government to eliminate terrorism has further strengthened after the death of Khanzada.
Khanzada was among 12 people killed on August 16 in a bomb attack that destroyed his office in Attock city.
