At least 20 Jordanians have been detained by Syrian security authorities since the start of protests in the country three weeks ago, Foreign Ministry spokesman
Mohammad Kayed said Sunday, dpa reported.
"The Jordanian ambassador in Damascus sent a memorandum to the Syrian Foreign Ministry two days ago asking about the whereabouts of 20 Jordanian citizens, but he did not receive a reply so far," he added.
Syrian authorities closed the border with Jordan two weeks ago after they alleged that arms were smuggled to Syria through the common border. Amman denied the claim.
Jordanian citizens from the border town of Ramtha demonstrated near the border on the past two Fridays to express solidarity with Syrian pro-democracy protesters, particularly in the adjacent city of Daraa.
