The Honduran government has formally declared Hezbollah a terrorist organisation, a top security official said on Monday.

"We declare Hezbollah a terrorist organisation and will include it in the registry of persons and institutions linked to acts of terrorism and its financing," said Luis Suazo, Honduras' deputy security minister.

Hezbollah has also been designated a terrorist organisation by the United States government.

Last week, Guatemala's new president, Alejandro Giammattei, also signalled he would label Hezbollah a terrorist group, in addition to keeping the Guatemalan embassy in Israel in the city of Jerusalem.

Both moves were seen as aligning Guatemala's foreign policy more closely with that of US President Donald Trump.

Israel's foreign minister, Israel Katz, called the Honduran government's move "an important step in the global war on terror" and said it built on similar actions taken in recent months by the United Kingdom, Argentina and others.

"I applaud the Honduran government for its important decision to declare Hezbollah a terrorist organisation and to impose sanctions against it," Katz said.

The UK's Treasury, or finance ministry, said on January 17 it had expanded an asset freeze to include the whole of Hezbollah, in addition to its military wing.

Last year, Argentina designated the group, which it blames for two attacks on its soil, as a terrorist organisation and froze its assets in the country.

Other countries that have designate Hezbollah or its military wing as a terrorist organisation include Canada, Australia, New Zealand, the European Union and Israel.
