A spokesperson for UN peacekeepers in Lebanon on Saturday said that Israel had requested it leave its positions in south Lebanon where Israel is clashing with Lebanese militant group Hezbollah, but they had refused.
They asked us to withdraw “from the positions along the blue line … or up to five kilometers (three miles) from the blue line,” UN Interim Force in Lebanon (Unifil) spokesperson Andrea Tenenti told Agence France-Presse (AFP), using the term for the demarcation line between both countries. “But there was a unanimous decision to stay,” he said.
That says the UN controls the troops.
They are not an army, they are a peacekeeping force.
They are also under UN rules, not their own nation’s.
If the UN decides they can choose to stay or leave, that’s what happens.
They are members of their own state militaries acting in an operation headed by the UN.
They have ROEs and similar orders handed to them.

Here’s a sample UN peacekeeping RoE for a recent exercise simulating an actual operation.

It’ll lay out the conditions under which one attacks and to what degree peacekeepers should hold maintain a position given the possibility that it is attacked, who they are authorized to engage, and such.
In this situation, you’ve got an active conflict underway between Hezbollah and Israel. Like, this isn’t going to be a “there’s nobody shooting at each other” situation. My point is that normally, countries are pretty particular about the lines for international conflict, and I’d expect an RoE to have specified whether they are expected to maintain positions during an evacuation order or not.
