 "US sanctions on Iran: Tehran, regional allies have started to feel the heat")
Giant posters on the streets of Beirut's southern Shi'ite suburbs display an armed Hezbollah fighter in uniform, holding the group's yellow banner and Lebanon's national flag, along with phone numbers where supporters can make donations to the Shiite guerrilla force.
"He who equips a warrior is part of the battle," the posters declare.
Hezbollah's calls for donations have intensified in past months as the group and its main backer Iran come under increasing financial pressure under sanctions from the Trump administration.
Washington has imposed sanctions on the militant group for decades. But a new wave this year appears to be more serious about targetting Hezbollah's top leadership, as well as businessmen and companies, that Washington says are funding the group.
The latest hit came October 15, when US Attorney General Jeff Sessions designated Hezbollah as one of five groups considered top transnational organised crime threats.
Iran, facing its own financial crises, has also reportedly cut back on funding for Hezbollah and Shi'ite militias it supports in Iraq.

Iran touts itself as the leader of the so-called "Axis of Resistance," grouping the Syrian government of President Bashar Assad, Shi'ite militias in Iraq, Hezbollah in Lebanon and Shi'ite gunmen in Yemen known as the Houthis.
The US State Department said in July that Iran has spent over $16 billion since 2012 supporting Assad and its proxies in Iraq and in Yemen, and it also gives $700 million a year to Hezbollah. It has also given the Syrian government $4 billion in lines of credit, it says.
Hezbollah's budget has already been hurt ever since it became heavily involved in Syria's civil war in 2013, sending fighters to back Assad's forces and helping turn the conflict in his favour. An estimated 2,000 of its fighters have been killed and thousands more wounded, some with permanent disabilities.
That only adds to the costs, since the group pays stipends to families of "martyrs" and provides health care for fighters.
Recently, its leadership started to publicly acknowledge the strain.
"I won't say that the sanctions will not have an effect ... They will have an effect for sure," Hezbollah leader Sheikh Hassan Nasrallah said in a speech in August.
He vowed the sanctions won't diminish the group's power. "We have the strength, infrastructure and human resources to get through these difficulties, God willing," he said.
In a closed meeting around the same time, he told Hezbollah cadres, "We have to tighten belts a bit," according to Ibrahim Bayram, an expert on Shiite affairs who writes about Hezbollah for Lebanon's An-Nahar newspaper and was informed about the meeting.
The group is taking measures to reduce expenses, such as bringing down the number of fighters in Syria, especially now that Assad's military has taken back greater territory from his opponents, Bayram told The Associated Press. But he said it was not cutting back on stipends for families, medical care and retirement payments.
A Lebanese citizen who has relatives in the group said it has pulled back some fighters in Syria, though it maintains its presence in eastern Deir el-Zour province and in the south, where fighting continues with the Islamic State group, and in Quseir, a town near the border with Lebanon that has been a Hezbollah stronghold for five years.
It has also asked some full-time fighters to spend more time at home when there is no need for them and has reduced movements of vehicles to cut transportation costs, he said. He spoke on condition of anonymity to discuss the group's internal activities.
