I recently saw the following sentences on the internet. The first is from an United Nations article :
"Despite that progress, however, there had had been heightened tension and unrest in the north of the country, said Mr. Fall..."
and from the BBC,
"The militant group, Islamic Jihad, which had had beenholding the journalist announced his release in a statement delivered to a news agency in the capital, Beirut."
1) Is 'had had been' correct or a typing error?
2) If 'had had been' can be used, how is it used?
I can't find anything on it in my grammar books but the internet has many examples of 'had had been'.
