Washington: The United States on Tuesday branded the son of Hezbollah's leader a "terrorist" subject to sanctions as it offered rewards to capture three militants in Lebanon with close ties to Iran.
In a series of back-to-back actions, the US vowed to aggressively counter the regional ambitions of Iran a week after imposing sweeping measures intended to cripple the country's economy.
It also marked a new US pressure tactic inside Lebanon, whose prime minister-designate, Saad Hariri, has been at a political crossroads with Hezbollah - considered a terrorist group by Washington.
The State Department declared Jawad Nasrallah, the son of Hezbollah's leader Hassan Nasrallah, to be a "global terrorist," meaning any US-based assets will be blocked and Americans will be forbidden from any transactions with him.
"Hezbollah's destructive actions have endangered the Lebanese people," Nathan Sales, the US ambassador-at-large and co-ordinator for counterterrorism, told reporters.
He accused Hezbollah - the only one of Lebanon's political parties that did not disarm after the 1975-1990 civil war - of "effectively using civilians as human shields" by hiding missiles in population centres.
"Hezbollah's ability to destabilise is not confined to the Middle East, however. It is able to destabilise inside Lebanon itself," he said.
Sales also held up "Wanted" posters for three men in Lebanon for which the United States will offer $5 million for information leading to their location.
They included Hamas deputy leader Saleh al-Aruri. The United States linked Aruri in particular to the 2014 murder of three Israeli teenagers in the West Bank including one, Naftali Fraenkel, who was a dual US-Israeli citizen.
Also on the posters were Khalil Yousif Harb and Haytham Tabatabai, both accused of commanding Hezbollah's growing military operations around the Middle East.
The Treasury Department separately placed sanctions on four men it said were key to Hezbollah's activities in Iraq.
Those four were Shibl Muhsin Ubayd Al-Zaydi, Yusuf Hashim, Adnan Hussein Kawtharani and Muhammad Abd-Al-Hadi Farhat.
The Treasury said Al-Zaydi was a key co-ordinator among Hezbollah, Iran's blacklisted Revolutionary Guards and their supporters in Iraq, and that the other three provided intelligence.
President Donald Trump's administration has vowed to roll back Iranian influence in the Middle East and last week snapped back sanctions, which had been lifted after Tehran entered a deal on ending its nuclear program.
Sales, using a figure previously cited by the administration, said that Iran pays $700 million a year for Hezbollah.
Hariri earlier Tuesday accused Hezbollah of holding up a new cabinet after five months of wrangling.
