Jordan says it has expelled the Syrian ambassador over "repeated insults" against the kingdom.
The Jordanian foreign ministry said it considered Bahjat Suleiman a persona non grata and gave him 24 hours to leave the country.
It said he had made numerous false allegations, accusing Jordan of harbouring Syrian rebels.
Syria has responded by expelling the Jordanian charge d'affaires in Damascus.
The Syrian ministry of foreign affairs denounced the decision to expel Mr Suleiman as "unjustified", Syrian state media said.
