Jordan launched air strikes on southern Syria on Monday evening in what it called retaliation for last week's deadly church attack in Karak. Syria's Civil Defence said the raids in Deraa and Suweyda provinces killed at least seven people, including three children and a woman.
Jordan's armed forces said they targeted armed groups' hideouts in southeastern Syria in coordination with the Syrian government. Damascus disputed that, saying the operation was carried out without prior coordination or notification and that it had opened an investigation. A Syrian foreign ministry official called the strikes a "treacherous attack".
Five of the dead, a man, a woman and three children from one family, were killed when a tent was hit in the village of Al-Tai in Deraa, the Civil Defence said. An 80-year-old man died in another strike, and a 60-year-old man was killed in the town of Shahba in Suweyda.
After the strikes, Syria closed the Nassib crossing in both directions. It is the only passenger and commercial crossing between the two countries.
Earlier on Monday, Jordanian forces arrested two brothers and their brother-in-law in the village of Al-Jadeeda after a gunfight of about three hours, on suspicion of involvement in Friday's attack. Three gunmen had opened fire on mourners at a funeral in a Greek Orthodox church in Karak, killing at least nine people, and King Abdullah II vowed the harshest penalties for those responsible.
