Iran has given Hezbollah the go-ahead to escalate attacks along Israel's northern border, according to reports.

The proxy militia in Lebanon backed by Iran is said to be poised to increase its cross-border assaults should it become certain Israel will invade the city of Rafah in the south of Gaza.

Hezbollah and Israeli forces have exchanged fire repeatedly in the months since the Gaza war began following the Hamas attack on Israel on October 7.

However, the Lebanon-based Shia militia have stopped short of all-out conflict with the Israeli Defence Forces (IDF) until now.

According to a report by the Arabic Post on Wednesday, high-level Iranian and Lebanese sources disclosed that Tehran has set conditions for Hezbollah, ordering the group to launch a large-scale attack on Israel only after confirming Israel's intentions to invade Rafah.

A meeting between Hezbollah Secretary-General Hassan Nasrallah and Iran's IRGC Quds Force commander Esmail Qaani was held to discuss “the latest developments,” a source from Iran's Revolutionary Guard revealed to Arabic Post.

Nasrallah reportedly expressed certainty about Israel's intentions to launch an assault on Hezbollah in Lebanon and sought Iran's support in responding effectively. "Nasrallah said that he is completely certain of [Israel's] intention to launch a large-scale attack on Lebanon, and he asked Qaani to give him complete freedom in how he intends to attack," a diplomatic source in Iran disclosed.

The report also highlighted Tehran's disapproval of Hezbollah's recent uncoordinated rocket launch on the northern Israeli city of Safed. The attack, which resulted in civilian and military casualties, led to Iranian calls for Hezbollah to exercise strategic patience.

The escalation in tensions underscores the volatile situation in the region, with fears of broader conflict looming large as Hezbollah gears up for potential retaliation against Israel.
