Qureshi, for his part, said Pakistan and Saudi Arabia established the Supreme Coordination Council, jointly led by Pakistani Prime Minister Imran Khan and the Saudi crown prince for fast track decisions in key areas of bilateral cooperation.
He offered his condolences over martyrdom of the members of Islamic Revolution Guards Corps in a suicide bombing near Iran-Pakistan border.
Reza Khaasteh, a Tehran-based journalist, said Jafari's latest statement, particularly on Pakistan, is "very harsh" as it "directly blames Islamabad" for the attack.
Jafari was addressing a large crowd gathered for the funeral of the victims of Wednesday's suicide bombing, which took place in a southeastern region where security forces are facing a rise in attacks by militants from the country's Sunni minority.
The chief commander of Iran's Islamic Revolution Guards Corps (IRGC) has warned Saudi Arabia and the UAE that they could face retaliatory measures for supporting terrorists on behalf of the United States and Israel.
The so-called Jaish ul-Adl terrorist group has reportedly claimed responsibility for the attack.
A day earlier, Iranian President Hassan Rouhani told reporters that unless Pakistan cracked down on the militant group, Iran would take action it "deems appropriate".
Pakistan's ambassador to Iran Riffat Masood said she would pass on the message, Tasnim reported.
The area has in the past witnessed several incidents and Pakistan had a year ago in October helped Iran recover some of the guards abducted by Jaish al-Adl.
Both terror attacks have sparked global outrage against Pakistan and accused it of supporting the perpetrators.
According to the Iranian media, Jaish-al-Adl, a separatist militant group which receives support from Pakistan, claimed responsibility for the deadly assault.
Islamabad has condemned the attack and vowed to cooperate.
Elsewhere, he referred to the abduction of 12 Iranian border guards, five of whom have already been released and returned home, while the 7 others are still being held captive by a terrorist group inside Pakistan. At least three police officers were wounded in a January 29 attack in Sistan-Baluchistan's capital, Zahedan.
Despite its constant balancing act of preserving itself from the Saudi-Iranian rivalry, Islamabad finally appears to have moved too close to Riyadh to easily mend relations with Tehran.
The allegations by Iran, a "chief sponsor of terrorism", sought to divert the attention of the Iranian people from the country's own troubles, said Adel al-Jubeir, the Saudi minister of state for foreign affairs.
"Enough is enough", Iranian Deputy Foreign Minister Abbas Argachi wrote on Twitter.
