A fragile truce between Israel and Hezbollah appeared to hold on Tuesday despite Israeli air strikes on southern Lebanon, as British-led diplomacy sought to prevent a broader escalation. The strikes, which hit areas near the Litani River, were the first since a UN-brokered cessation of hostilities came into effect 48 hours ago. No casualties were reported.
The Israeli military described the operation as a “precise” response to a suspected Hezbollah rocket launch, which it said had violated the ceasefire. Hezbollah denied involvement. The exchange underscores the brittleness of the truce, which ended the heaviest cross-border fighting since the 2006 war.
UK Foreign Secretary James Cleverly held separate telephone calls with his Israeli and Lebanese counterparts on Tuesday, urging restraint. Downing Street confirmed that Britain had offered to deploy a small team of military observers to the UN Interim Force in Lebanon (UNIFIL), which patrols the border. The proposal is seen as an attempt to strengthen the existing ceasefire mechanism, which critics say lacks enforcement powers.
“The UK is using its full diplomatic weight to prevent a return to conflict,” a Foreign Office spokesperson said. “We recognise the deep security concerns on both sides, but the path to stability lies in de-escalation and dialogue.”
In Beirut, the Lebanese government welcomed the British initiative but warned that any sustained Israeli action risked “igniting the entire region”. Hezbollah’s political arm, which has significant influence in the coalition government, has signalled its willingness to maintain the truce provided Israel does not expand its operations. However, the group’s military wing has warned of retaliation for any strikes that kill its fighters.
On the ground, the situation remained tense. Residents of southern Lebanon reported hearing explosions from the Israeli strikes, which targeted open areas near the border. In northern Israel, air raid sirens sounded briefly but no rockets were detected. Schools remained closed on both sides of the border, and UNIFIL patrols were suspended amid security concerns.
Analysts say the truce’s survival depends on whether both sides see political advantage in restraint. Israel, which has faced international criticism over the scale of its operations, is wary of a prolonged campaign that could drain resources from other priorities. Hezbollah, meanwhile, is mindful of Lebanon’s economic collapse and the risk that a new war could devastate its political standing.
“The UK’s role here is critical,” said Dr. Elizabeth Monaghan, a senior fellow at the Royal United Services Institute. “Britain has the credibility to speak to both sides, and its offer of observers could provide a face-saving mechanism. But if either party calculates that the costs of peace outweigh the costs of war, the truce will collapse.”
Diplomatic sources said the next 72 hours would be decisive. The UK is expected to hold further talks with regional powers including Saudi Arabia and Qatar, which have influence over Hezbollah’s backers in Iran. A British official cautioned that expectations for a lasting settlement should be “modest”, but added that even a temporary pause in fighting would allow humanitarian access to affected areas.
The UN Security Council is due to discuss the situation behind closed doors on Wednesday. Secretary-General António Guterres has called for an immediate return to the ceasefire and warned that any further escalation would have “catastrophic consequences”.
For now, the truce holds. But as the Israeli air strikes show, the border remains a hair-trigger. The question is whether British diplomacy can turn a fragile pause into a durable calm.
