Iran took advantage of the bombing, which targeted Zahedan last Wednesday and killed 27 Revolutionary Guards soldiers, to accuse Pakistan of being involved in the attack.
To protest the bombing, Tehran summoned the Pakistani ambassador on Sunday.
"Jaish al Adl" which says it seeks greater rights and better living conditions for the ethnic minority Baluchis, claimed responsibility for the attack earlier.
Iran says militant groups operate from safe havens in Pakistan.
“The government of Pakistan must pay the price of harboring these terrorist groups and this price will undoubtedly be very high,” Iranian state television quoted Major General Mohammad Ali Jafari as saying.
Jafari blamed Pakistan’s army and Inter-Services Intelligence agency, saying that “sheltering and silence” amounts to supporting the perpetrators.
Jafari also accused Saudi Arabia and UAE of supporting opposition groups that attack Iranian forces, threatening to retaliate against them over the attack.
Saudi Political Analyst Dr. Khaled al-Habbas told Asharq Al-Awsat that Iran is trying to adopt a counter-strategy due to international and regional pressures, which left it in a state of frustration.
“The recently held Warsaw meeting had one main objective, which is facing Iranian regional threats,” Habbas stressed, noting that it added pressures on Tehran.
“Saudi Arabia and the UAE are among the countries seeking to highlight the destructive Iranian role in the region, so it is easy for Iran to indict Riyadh and Abu Dhabi only to try to adopt a counter-policy," he said.
Dr. Habbas did not rule out that the regime’s accusations against Pakistan aim to disrupt the upcoming Saudi Crown Prince’s visit to the country.
Researcher on terror affairs Dr. Yousef al-Rumaih, for his part, told Asharq Al-Awsat that the Iranian regime always tries to influence the public opinion by raising baseless accusations against foreign parties, in hope to overcome its internal issues.
He said that everyone knows the size of internal and foreign opposition against the Iranian regime, in addition to its many economic and social problems, so it accuses other parties to find a way out of the crisis.
