Iran's Foreign Minister Mohammad Javad Zarif expressed "grave concern" about the fate of Jamshid Danayifar, who was kidnapped along with four other border guards on February 6 by rebel group Jaish-ul Adl.
"We did all we could to secure their release," Zarif told state television after a cabinet meeting.
"But it is disappointing that the Pakistani government has failed to secure its borders, and allows terrorists to operate on its soil."
Zarif's remarks came after his ministry summoned Pakistani ambassador Nour Mohammad Jadmani, demanding "swift and serious action" to secure the release of the soldiers, the official IRNA news agency reported.
Jaish-ul Adl said on its website on Sunday that Danayifar had been killed, warning of further executions should Tehran refuse to "release Sunni prisoners".
Iran's interior ministry says it is awaiting Islamabad's official position amid media reports that local Pakistani authorities have confirmed the group's claim.
The rebel group, which took up arms in 2012 to fight for what it says are the rights of Iran's minority Sunni population, is active in the restive Sistan-Baluchestan province that borders both Pakistan and Afghanistan.
UN Secretary General Ban Ki-moon yesterday in a statement condemned the reported killing as an "appalling act" and urged that the perpetrators are brought to justice.
A spokesman for the US State Department, Alan Eyre, called for the "swift release" of the abducted soldiers while expressing hope the reported execution -- that came as Iran was celebrating its Persian New Year -- was not true.
Shortly after the abduction, Iranians launched a campaign on Twitter, despite the micro-blogging service being banned in Iran.
Some Iranians have used social media to hit out at the Tehran government for its inability to bring home the young soldiers, who were serving their 24-month mandatory military service.
Border guards chief Hossein Zolfaghari has admitted that there was "negligence" in the lead-up to the kidnapping, saying those responsible were suspended, with some facing prosecution.
