Ari Haswari was a rogue Israeli-born Mossad officer and a terrorist who was also a sworn nemesis of NCIS Special Agent Leroy Jethro Gibbs.

Ari's wave of terror which had started when he invaded the NCIS morgue, triggering a hostage situation and had continued on for nearly two years finally came to a permanent end when he was ultimately killed in a confrontation with Gibbs and Ari's fellow Mossad Officer/half-sister Ziva David in September 2005.

He was the son of Eli David and Hasmia Haswari, the older half-brother of Ziva and Tali David, the younger half-brother of Sergei Mishnev, and the uncle of Tali David-DiNozzo.



Born in 1969, Ari was the only son of Dr. Benjamin Weinstein which was the undercover alias of Mossad agent Eli David and Dr. Hasmia Haswari, an Arab with the two having met while they were working together at a hospital in Jerusalem.

Ari gained two half-sisters from his father's first marriage: Ziva and Tali with the three forming a strong kinship and harboring loyalty towards one another.

Unfortunately, Tali died in a suicide bombing at the age of sixteen, her murder devastating both Ziva and Ari.

In 1994, Ari graduated from Edinburgh Medical College, the same college NCIS Medical Examiner Dr. Donald Mallard had graduated from years earlier.

After that, Ari did his post-graduate work at the Edinburgh Center with a colleague of his, Dr. Martin Sedgewick mentioning Ari was a brilliant ladies man who only answered to his surname instead of his first name.

Upon leaving the center, Ari traveled to the Gaza Strip and began working with his mother at a local clinic there. He soon began harboring feelings of resentment towards Eli as Ari believed that like Ziva and Tali, Eli had shaped him to become a Mossad mole inside Hamas with Ari soon beginning to secretly to work against his father.

In early 2000, a missile strike from Israel killed Hasmia, her death leaving him devastated.

Ari soon began to believe Eli had personally arranged the strike itself to give his son a perfect reason for joining while still working undercover as a Mossad officer.

Unfortunately, this had the opposite effect as Ari, fueled by the need for revenge against his father subsequently turned against Eli, becoming a double agent for Mossad and also some unnamed terrorist groups, one in question being al-Qaeda with Ari binding his time and waiting until he was in the position to not only strike back at Israeli but at his father too.
