On the outskirts of this southern Lebanese village, workers in a pickup truck parked at a nature reserve named after a fallen fighter of the Hezbollah terror group. They took two large eucalyptus tree seedlings out of the truck and planted them.

The men are from Green Without Borders, a non-governmental organization that says it aims to protect Lebanon’s green areas and plant trees.

But Israel, the United States and some in Lebanon accuse the NGO of being an arm of Hezbollah to hide its military activities. They say the organization has been setting up outposts for the terror group along the border with Israel. Last month, residents in the southern Christian village of Rmaych near the border said they encountered armed men at an outpost of the organization that was blocking them from farmlands.

Green Without Borders denies any link to Hezbollah, which also says it is not connected to the environmental group.

“We are not an arm for anyone,” the head of Green Without Borders, Zouher Nahli, told The Associated Press. “We as an environmental association work for all the people and we are not politicized.” He spoke at the Bassam Tabaja Nature Reserve, named for a Hezbollah fighter killed in Syria in 2014, where the NGO has planted hundreds of trees.

He said the organization’s funding comes from the ministries of environment and agriculture as well as from wealthy Lebanese who care about the environment and municipalities, mainly in the eastern Bekaa Valley and southern Lebanon. He said he is an Agriculture Ministry employee.

In a November report, UNIFIL said shipping containers and prefabricated buildings, some of them with visible Green Without Borders markings, had been set up at 16 sites along the border. In several instances, UNIFIL patrols were prevented from nearing the locations, it said.

The Israeli military says Green Without Borders outposts on the border are used by Hezbollah to gather intelligence information.

At a Security Council meeting in September, the U.S. deputy U.N. ambassador, Richard Mills, said the proliferation of the group’s outposts along the border obstructs UNIFIL access and “is heightening tensions in the area, further demonstrating that this so-called environmental group is acting on Hezbollah’s behalf.”

At the meeting, the council unanimously approved a resolution strongly condemning harassment, intimidation, attacks and restrictions on UNIFIL.

Last month, an Irish U.N. peacekeeper was killed and several others were wounded when attackers opened fire on a UNIFIL convoy in southern Lebanon. Hezbollah denied any connection to the attack.

Residents of the Christian village Rmaych have complained for years about a position set up by Green Without Borders on farmland belonging to village families in a nearby valley. They say the organization did not plant any trees there and actually chopped down trees and cut a 1.5-kilometer (1-mile) dirt road on their land.

“It is a cover for Hezbollah to have positions. We have no problems with Hezbollah, but it should be outside our lands,” said Bassam al-Haj, a Rmaych schoolteacher.

In December, al-Haj and other residents went to the outpost and confronted the men there. Al-Haj said some of the men at the site were masked and armed, and that the outpost included several rooms, a tent and a fence that blocked off village farmland.

The residents and the men argued, he said. One resident who was videoing the encounter was told by one of the men, “We will crush you if you don’t delete the photos that you took,” al-Haj said.

Days after the confrontation, a Hezbollah official and members of the organization visited the village and met residents at the mayor’s office, said Father Najib al-Ameel, a priest from Rmaych who attended the talks.

The mayor and residents asked that the post be removed, he said. Al-Ameel said he told the Hezbollah official, “We will not accept anyone but the Lebanese army to protect us.” A few days later, Green Without Borders removed the post and now residents can freely access their land, he said.
