What happened during a transport strike in Algeria (4)
I believe the answer is:
Here is my best explanation:
'in algeria' is the definition.
('Oran' is part of 'algeria')
'what happened during a transport strike' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is located in the answer.
The remaining letters 'or' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
