John Hurley, Undersecretary for Terrorism and Financial Intelligence at the US Treasury, is set to begin a tour of several Middle Eastern and European countries aimed at intensifying pressure on Iran, the US Treasury said in a statement.

Hurley, the Treasury Department’s top sanctions official, will visit Israel, the United Arab Emirates, Turkey, and Lebanon as part of the Trump administration’s renewed “maximum pressure” campaign against Tehran. The initiative seeks to prevent Iran from developing nuclear weapons while targeting its regional proxies.

"President Trump has made clear that Iran's destabilizing and terrorist activities must be met with sustained and coordinated pressure," Hurley said in the statement.

"I look forward to meeting with our partners to coordinate our efforts to deny Tehran and its proxies the financial access they rely on to evade international sanctions, fund violence, and undermine stability in the region."

In Israel, Hurley is expected to discuss ways to strengthen the campaign against Iran, with a particular focus on its network of regional proxies.

In Lebanon, US political and economic pressure to curb Hezbollah’s military capabilities has reached unprecedented levels, said officials cited by the Central News Agency, coinciding with heightened Israeli threats of renewed military action against the group’s arsenal. Hurley’s stop in Beirut is seen as part of a coordinated effort to squeeze Hezbollah economically and politically.

“Maximum pressure” is understood by Washington as encompassing not only military measures but also financial and political levers, the sources said. Hurley is expected to urge Lebanese authorities to intensify steps to cut off all funding channels for Hezbollah, including those through airports, land borders, and money transfer companies. While Lebanon has begun implementing such measures, the US official is anticipated to commend progress while insisting that the efforts be completed and expanded.

Sources familiar with the matter said the US is targeting Hezbollah-affiliated social institutions, including Al-Qard Al-Hasan and other social service organizations, which Washington considers potential fronts for money laundering and funding for the group. Hurley is also expected to warn Lebanese officials that delays or insufficient cooperation could trigger US sanctions on the country.

The political sources emphasized that the current phase of intense pressure on Lebanon is intended to continue “until Hezbollah’s military power is dismantled.”
