Larijani met Lebanon's president Joseph Aoun, prime minister Nawaf Salam and the parliament's speaker, Hizbollah-associated Nabih Berri.
Lebanon rejects all interference in its internal affairs, was the message from Lebanon's president.
–It is forbidden for everyone ... to carry weapons and to use foreign support as leverage, explained Aoun.
Larijani claimed that the disarmament decision is dictated from the USA, something that was strongly rejected by prime minister Nawaf Salam.
Hizbollah has responded to the disarmament plan by saying that the government's decision will be handled "as if it did not exist". Last week, an advisor to Iran's supreme leader also declared that Iran opposes the plans to disarm Hizbollah.
Hizbollah has until the latest war been considered better armed than Lebanon's own army, and the Iran-supported group has claimed to protect Lebanon. The movement has been completely terrorist-stamped by several countries, while others have chosen to only terrorist-stamp its armed branch.
