Five subordinate clauses

The interior ministry said in a statement it “confirms that this terrorist network, whose terrorist plan was thwarted, violated, in what they would have perpetrated, all sanctities by targeting the security of the Grand Mosque, the holiest place on Earth. (The Guardian.)

There are five subordinate clauses in the sentence above:

- it confirms that this terrorist network ... violated... all sanctities...

- this terrorist network... violated... all sanctities....

- whose terrorist plan was thwarted

- they would have perpetrated

- targeting the security...
