The discovery was made by special units of the National Directorate of Security in Police District 12 of the city, the agency said in a statement.
Two members of Haqqani network who were tasked to carry out the attack were arrested, it said.
The network had planned to carry out an attack similar to that of a truck bomb attack outside the German embassy in May 2017 that killed at least 150 people, according to the statement.
