Hezbollah is facing mounting pressure as Syria's new government, which opposes both Iran and Hezbollah, increases military activity along the Syrian-Lebanese border. Tensions have risen in recent weeks amid broader strains between Washington and Tehran, as well as Israeli warnings that Lebanon would face retaliation if Hezbollah intervenes in any new regional conflict. Pro-Hezbollah media report growing concern within the group over Syrian troop movements and new positions established near Homs.

A key flashpoint involves what Syrian authorities call the 'Mezzeh cell,' a group accused of militant activity near Damascus. While Syrian officials have suggested links to Hezbollah, allied media deny the claims and argue the suspects are tied to other armed factions. Hezbollah fears Damascus could use such allegations, including potential discoveries of drones or missile components, as justification for future security operations targeting the group.

The situation is further complicated by Syria's cooperation with the United States-led coalition against the Islamic State group and the arrival of foreign fighters in border areas. With new governments now in both Beirut and Damascus that are less aligned with Hezbollah, the movement appears increasingly wary that shifting regional alliances and security campaigns could isolate it politically and militarily.
