The declaration follows a meeting of the coalition, reported by Al-Manar, a Hezbollah-affiliated network funded by Iran.
The IRCC is a coalition of Iranian-backed Iraqi militias, part of Tehran’s broader strategy to exert influence in the Middle East and counter US and allied presence.
Key groups within the IRCC include Harakat al-Nujaba (HaN), Kata'ib Hezbollah (KH), and Kata'ib Sayyid al-Shuhada (KSS).
The committee’s statement comes in response to escalating tensions along the Israel-Lebanon border. The border has seen daily exchanges of fire between Israeli forces and Hezbollah since the outbreak of the Gaza conflict on October 7.
Fears of a full-scale war intensified after Israeli Prime Minister Benjamin Netanyahu announced preparations for "a very tense operation" on the Lebanon border.
Iran's UN mission has warned Israel against “full-scale military offensive” in Lebanon, saying it would lead to an “obliterating war”.
“All options, [including] the full involvement of all Resistance Fronts, are on the table,” the Iranian mission said in a post on its X account on Friday.
