Jordanian Foreign Minister Nasser Judeh said on Thursday that his country had withdrawn its monitors from the Arab League mission to Syria, saying the decision had been taken several days ago when the work of all monitors was suspended.
"There is no mission and we withdrew in conformity with the Arab League decision," Judeh told Reuters.
On Saturday, the Arab League announced that it had suspended its mission in Syria due to rising violence, but the mission has not been formally declared over.
Earlier last week, Gulf states withdrew their monitors from the country, saying the team could not stop the violence - which Assad blames on foreign-backed militants.
Jordan, which has a long border with Syria, had accepted the Arab League peace plan for Syria, which calls for President Bashar Assad to step down in favor of a unity government. However, it fears antagonizing Assad and also is concerned that instability might spill over its frontier.
King Abdullah has also said his country is opposed to foreign intervention in Syria.
The Arab League suspended its month-old mission in Syria because of worsening violence, a move Damascus said was an attempt to encourage foreign intervention.
