According to Jerusalem Post, the woman identified as Saja al-Dulaimi, an Iraqi, was reportedly traveling with a fake passport when she was arrested and detained in coordination with "foreign intelligence", according to a senior Lebanese political source and security official.
A Lebanese security official said that a DNA test was conducted on the girl traveling with the woman to verify it was Baghdadi's child. It proved positive.
The arrest is a blow to the terror leader as the wife and daughter could be used against his group, especially as a bargaining chip. The terror group has captured many foreigners.
There is currently no immediate reaction from Islamic State websites.
