Yasir Qassam was a terrorist (presumably associated with Hamas) who worked at the Norfolk Naval Base, selling French fries and burgers to American and Israeli sailors while planning a terrorist attack at the Base.
Qassam was born in the Gaza Strip with his parents dying during the Second Intifada when their home was shelled.
Qassam's brother, Saleem was recruited by Hamas and ended up becoming a suicide bomber, dying when he blew himself up along with several Israeli citizens on a bus in Jerusalem.
Qassam later entered the US illegally, having had his documents forged in Mexico when he was unmasked by an Al-Qaeda detainee.
NCIS Season 1Edit
NCIS Special Agent Paula Cassidy who was at Gitmo informed her NCIS colleagues of the news and as such, NCIS devised a plan to capture him and launched a stop at the Norfolk Naval Base.
Unfortunately, Qassam saw that the check was anything but routine and attempted to fight back, forcing Leroy Jethro Gibbs to kill him by shooting him in the heart.
His body along with his personal belongings were all taken to NCIS where Donald Mallard intended to do an autopsy to find out the full details of his death, but due to the fact that Hamas feared that they would discover that Qassam had knowingly infected himself with smallpox in hopes of launching a biological attack, terrorist Ari Haswari was sent to NCIS in a body bag to get Qassam's body, blood and personal belongings.
Haswari was not successful in getting any of Qassam's belongings back and was forced to flee while the smallpox virus had been confiscated and sent to CDC where it was presumably destroyed.
