AMMAN, May 1 (Reuters) - A group of Arab foreign ministers held a landmark meeting with their Syrian counterpart in Jordan on Monday to discuss how to normalise ties with Syria as part of a political settlement of the country's more than decade-old conflict, officials said. Jordan has called on Syria to engage with Arab states jointly on a step-by-step roadmap to end the conflict, tackling the issues of refugees, detainees, drug smuggling and Iran-backed militias in Syria - all of which affect its neighbours. Amman has been fighting armed groups smuggling narcotics from Syria, including the highly-addictive amphetamine captagon. Arab states and those most impacted by the conflict are trying to reach consensus on whether to invite Assad to the Arab League summit on May 19 in Riyadh, to discuss the pace of normalising ties with Assad and on what terms Syria could be allowed back. Washington, which said it would not change its policy towards the Syrian government which it terms a "rogue" state, has urged Arab states to get something in return for engaging with Assad.
