Iran welcomes any move that helps promote peace and stability in neighboring Afghanistan, the Foreign Ministry spokesman said.
Hossein Jaberi Ansari made the statement in a regular press briefing on Monday, referring to reports that the Afghan leader of the Taliban militant group, Mullah Akhtar Mansour, has been killed by a US drone attack in Pakistan's Balochistan on Saturday.
Afghan and US officials have asserted that Mansour is one of the two people killed in the attack, but Pakistan announced that it is unsure if the Taliban leader has been targeted.
Reuters reported the Pakistani Foreign Ministry as saying in a statement on Sunday that a passport found at the site of the attack bears the name of a Pakistani man named Wali Muhammad.
It added that the passport carries a valid Iranian visa and the purported holder was believed to have returned to Pakistan from Iran on May 21, the day of the drone strike.
The ministry did not comment on the possibility that Mansour might have been traveling under another name.
Asked to comment on Pakistan's claim, Ansari said Tehran has not allowed any person named Wali Muhammad to pass its borders on Saturday.
"The relevant bodies of the Islamic Republic reject that such a person has entered Pakistan from the Iranian border on such a date," he said.
