During an open session on Sunday morning, the parliament passed the bill with 187 votes in favor, 14 votes against and 6 abstentions.
The bill on Iran-Pakistan Security pact had earlier been adopted by the Iranian Council of Ministers and submitted to the parliament on March 31, 2013.
The bill contains a single article and 11 clauses in which the areas of cooperation, working methods, costs, the responsible ministries and other issues relating to the security pact are included.
In February 2013, Iran and Pakistan signed the security pact with the aim of boosting anti-terror cooperation.
The agreement, which was signed in Tehran between the Iranian Interior Minister and his Pakistani counterpart, was intended to take strict measures to combat terrorism, human and drug trafficking.
