Original text - English - ...must be late

This one needs some edit, doesn't it ?

I was on it, but apparently the requester does not speak English therefore she will not be able to correct it.
Perhaps:

"The bus was late. They don't know when they are going to Turkey. Kadem is OK and greets you. (sends his regards)"

But we would be guessing...

The rest of the text is OK but the first sentence could be ''...must be late''... Perhaps we should remove it (only the first sentence, as the rest is understandable)..?

'must be late" I should have thought of that!
