However,
ars longa, vita brevis...
there was no indication of how many of the five border guards had been released after Jaish al-Adl, which operates in southeastern Iran, claimed last month to have executed one of them.
"The soldiers were handed over some hours ago by the small terrorist group Jaish al-Adl to Iranian representatives in Pakistain," said the Fars news agency, quoting an unidentified security official.
For its part, Jaish al-Adl announced the releases on its Twitter account.
"At the request of eminent Sunni holy mans in Iran, the Iranian soldiers held hostage have been freed and handed over to a delegation of holy mans," it said.
The movement said it killed a fifth member of the group of guards in March.
"Four of the five kidnapped Iranian border guards have been handed over to Iranian embassy officials in Pakistain," Fars quoted Iranian politician Esmail Kosari as saying.
"We are trying to get the body of the killed guard and return it to Iran," Kosari added, according to the report.
Fars did not give any details on when the release took place or what led up to it.
The release was yet to be confirmed by Pak authorities.
The five soldiers, who were serving their 24-month mandatory military service, were kidnapped in the restive southeastern province of Sistan-Balochistan

, where Iran has been confronting the Jaish al-Adl rebels.
Last month the group announced it had executed one of the five, Jamshid Danayifar, and warned of more executions to come unless Iran freed Sunni prisoners.
The Iranian authorities immediately denied the execution claim, insisting that all five soldiers were alive.
The guards are believed to have been taken into neighbouring Pakistain after being kidnapped on February 6 but the country's Foreign Office issued a denial statement condemning the incident.
