Australian Teenager Jake Bilardi died in a suicide bombing in Iraq. Here are five things we know about the 18-year-old Islamic State terrorist. IN PHOTO: A man purported to be the reclusive leader of the militant Islamic State Abu Bakr al-Baghdadi has made what would be his first public appearance at a mosque in the centre of Iraq's second city, Mosul, according to a video recording posted on the Internet on July 5, 2014, in this still image taken from video. There had previously been reports on social media that Abu Bakr al-Baghdadi would make his first public appearance since his Islamic State in Iraq and the Levant (ISIL) changed its name to the Islamic State and declared him caliph. The Iraqi government denied that the video, which carried Friday's date, was credible. It was also not possible to immediately confirm the authenticity of the recording or the date when it was made.

Islamic State mastermind Abu Bakr al-Baghdadi's wife and son were detained in Lebanon. The Iraqi woman, one of al-Baghdadi's three wives, was identified as Saja al-Dulaimi.

The Lebanese army detained both of them while as they crossed the Syria border nine days back. According to the local newspaper As-Safir, al-Baghdadi's wife was detained while the military worked in coordination with "foreign intelligence." Reuters reported that the detention was a setback to the Middle Eastern extremist group and its leader. The arrest can be used to set a bargaining offer against Islamic State which is known for capturing numerous foreign citizens in the prisons of Syria and Iraq. A senior security official in Lebanon contradicted earlier reports by claiming that al-Dulaimi was accompanied by her daughter. The official also said that DNA tests had confirmed that it was al-Baghdadi's child. It is unclear when exactly the Lebanese authorities captured al-Baghdadi's wife and child. According to multiple media sources, the detention may have taken place in the last couple of weeks.

Islamic State has not yet reacted to the report while al-Baghdadi's wife had been interrogated at the Lebanese defence ministry. She happens to be one of 150 women who were released from a government jail in Syria in March. The release was a bargaining deal to set free 13 nuns captured by Islamic State. A source close who has contacts in Iraqi intelligence confirms that she is one of al-Baghdadi's wives. However, he has not been able to confirm her name. It was a cooperative effort by Lebanon and Iraq to capture al-Baghdadi's wife. According to terrorism expert Sajjan M. Gohel, the arrest is a major advancement. "It's certainly a new dynamic because we've never seen anybody connected so close to al-Baghdadi being detained," CNN quoted Gohel.

Earlier U.S. media reports claimed that al-Baghdadi had been captured for many years at Camp Bucca in southern Iraq. His detention at the U.S.-run prison had taken place before he became the head of the Islamic State of Iraq in 2010. al-Baghdadi is known as a ruthless leader who does not think twice before eliminating opponents.

Lebanon has also been able to detain senior Nusra Front leader Anas Shirkas' wife. However, the woman was not identified.
