Syria closed its Nassib border crossing with Jordan on Tuesday 27 October, suspending passenger and commercial traffic in both directions. The crossing, on the Damascus–Amman highway, is the only crossing between the two countries serving both passengers and cargo.

The closure followed Jordanian airstrikes on Monday evening in southern Syria. Jordan said its air force struck what it described as militant hideouts after determining that suspects behind last week's deadly attack on a church in Jordan were linked to groups operating in southern Syria. Jordan's government said more than 20 Islamic State militants were killed. Syria said seven people, including three children and a woman, were killed.

Two governments, two accounts

The two governments disagree on a central point: whether Damascus was consulted beforehand. Jordan's armed forces said the operation was conducted in coordination with Damascus. Syria's government said the strikes were carried out without coordination, and that it had opened an investigation.

Jordan said it regretted civilian casualties. The dispute leaves the immediate future of the crossing unclear, with trade and travel disrupted while both sides pursue investigations and diplomatic contact. No reopening time was given in the closure announcement.
