Mir ist aufgefallen, dass Mazraat Deir al-Ashaer auf den meisten internationalen Karten auf libanesischem Gebiet liegt, obwohl es administrativ eine syrische Stadt ist, die zum Rif Dimashq gehört. Kennt jemand den historischen oder kartografischen Grund für diese Diskrepanz?

1.Lebanese government says it’s Syrian:
Lebanese State News Agency (NNA) reported on a visit by a Lebanese MP to the area, and they literally called it „the neighboring Syrian town of Mazraat Deir al-Ashaer.“ If the Lebanese state itself calls it Syrian, that’s as official as it gets.

2. The Lebanese Army treats it as a foreign border
Back in 2020 during the COVID-19 lockdowns, the Lebanese municipality of Deir al-Ashaer and the Lebanese Army actually blocked the roads connecting them to „the Syrian Mazraat Deir al-Ashaer“ to control the border. You don’t „close a border“ or set up military checkpoints against your own territory. The military reality on the ground is that Mazraat is on the Syrian side of the fence.

3. They are „Twin Villages“ with different identities
There are actually two towns right next to each other. The Lebanese one is „Deir al-Ashaer“ (mostly Druze) and the Syrian one is „Mazraat Deir al-Ashaer“ (mostly Sunni). This report from As-Safir explains the social dynamic perfectly how the Lebanese villagers actually used to rely on the Syrian side for hospitals and schools because the road to the rest of Lebanon gets blocked by snow in the winter.

4.This their Facebook official community page, they put the Syrian new flag and they clearly identified as Syrians: https://www.facebook.com/share/1AjDhCfXDs/
This is a video of the mayors from both villages, if you understand Arabic، there is a clear distinction between Lebanese “ Deir el Ashair“ and syrian „Mazr3et Deir el Ashair“:https://www.facebook.com/share/v/16jkZBVe2A/
