Jordan and Syria have agreed to form a joint security committee to examine the details and repercussions of recent Jordanian airstrikes against Islamic State sites in southern Syria, the two countries said in a joint statement early on Wednesday, according to Reuters. The agreement comes after days of rising tension between the neighbouring states, a disputed account of whether the strikes were coordinated in advance, and the closure of the only passenger and commercial border crossing between the two countries. It is the first formal step toward a shared account of what happened, and it will test whether two governments that disagree in public about the strikes can still cooperate on border security.

Jordanian Foreign Minister Ayman Safadi told his Syrian counterpart Asaad al-Shaibani that the strikes were based on field intelligence and aimed at neutralising confirmed threats and imminent attacks targeting Jordanian security, Reuters reported. Safadi also expressed deep regret over civilian deaths during the operations, a rare public acknowledgement from Amman that the raids carried a human cost on the Syrian side of the border. The joint statement did not set a date for the committee to meet, and it did not say what powers the body would hold or whether its findings would be made public.

How a church attack set off the crisis

Last week, gunmen opened fire on a funeral ceremony at a Greek Orthodox church in the southern Jordanian province of Karak, killing nine people and wounding dozens more, in an attack that stunned a country where such mass shootings are rare. Jordanian security forces later arrested suspects after a shootout, and Jordan said it had determined that the attackers were linked to terrorist groups operating across the border in southern Syria. King Abdullah II had promised harsh retaliation, and the government framed the cross-border operation as a direct response to a threat that had already reached inside Jordanian territory.

On Monday, Jordan said its air force struck what it described as militant hideouts in southern Syria, hitting targets it linked to the church attackers. The Jordanian military said the operation was conducted in coordination with Damascus, but the Syrian government gave a contradictory account, saying it had not been notified in advance and announcing an investigation into the strikes. The Syrian Civil Defence said seven people were killed, among them children and a woman, and several others were wounded, with emergency teams responding to sites in the countryside of Daraa and Sweida provinces. Damascus conveyed what it called its complete reservation over the strikes, and its foreign ministry described the raids as a violation of Syrian sovereignty.

A closed crossing and a test of trust

Shortly after the strikes, Syria closed the Nassib border crossing with Jordan, suspending passenger and commercial traffic in both directions, according to the Syrian General Authority for Border Crossings and Customs, which cited the security situation on the ground. Nassib is Jordan's only passenger and commercial border crossing with Syria, so the closure severed the main overland link for traders, travellers and families moving between the two countries. The crossing has long served as a barometer of the relationship: when it is open, commerce and movement flow, and when it shuts, the strain between the capitals is visible in empty lanes and waiting trucks.

The new joint security committee is meant to bridge that gap. Jordan's communications minister said it would examine the consequences of the operation and strengthen coordination in combating Islamic State fighters while protecting civilians, adding that Jordan's security and Syria's security are one. Syria's foreign ministry said the two sides were working to establish an urgent joint field and security committee to prevent further violations and secure the shared border. For now, the language from both capitals points in the same direction, even though the two governments still disagree about the central fact of whether the strikes were coordinated at all.

What happens next will show whether the joint security committee is a genuine forum or a diplomatic holding measure. Its first tasks are likely to include agreeing on a shared account of the strikes, deciding how civilian casualties are investigated, and setting conditions for reopening the Nassib crossing. Traders and border communities have the most immediate stake in those decisions, since every day the crossing stays shut adds cost and uncertainty to cross-border trade. The wider region will also be watching, because the episode has raised a question that reaches beyond one border: how neighbouring states handle militant threats that cross frontiers without turning a security operation into a diplomatic rupture of its own.
