Can no longer open Pages documents in LibreOffice

I used to be able to open documents created and saved as 'Word' documents in Pages with LibreOffice Writer.

This is no longer possible.

I can still open other documents created with Microsoft office and saved with the .doc extension in LibreOffice Writer.

Is Pages now saving the documents in a non stanard 'Word' format?

I have the latest version on the Word App on my iPad and I am using LibreOffice Writer Version 3.6.2.2 (Build ID: 360m1(Build:2))
