Hezbollah leader Hassan Nasrallah traveled to Iran around two months ago when Tehran asked him to respond to any possible Israeli strike on Iran nuclear sites.

Israel’s Channel 12 News reported on Wednesday that during his rare visit the Iranians told him they expect Hezbollah to respond militarily in case of a possible Israeli strike on Iran’s nuclear facilities.

The report, which did not cite sources, described Nasrallah’s trip from his secure, secret location in Beirut to Tehran as “definitely unusual”, noting that the Islamic Republic informed the Hezbollah chief that it is time that the Shiite group returns years of Iran’s investment.

The Israeli site did not say what the outcome of the meeting was or what Nasrallah agreed to with the Iranians.

In an interview with Iran’s Arabic-language al-Alam news network earlier in February, Nasrallah said Hezbollah would not necessarily become involved if Israel hits Iran’s nuclear sites but noted he didn’t think Israel was serious about attacking.

In a televised speech to followers earlier on Wednesday, Nasrallah said for the first time, that it can convert thousands of rockets into precision missiles within Lebanon.

"We have been producing drones in Lebanon for a long time, and whoever wants to buy them, submit an order," he said.

Hezbollah and Israel fought a month-long war in 2006 and have at times in the years since traded fire across Lebanon's southern border.
