The head of Hamas' rocket unit and one of the organization's military wing's senior operatives, Ayman Siam, was hit Tuesday morning in an aerial attack on a building in the Jabaliya neighborhood in the northern Gaza Strip.
Siam also served as commander of Hamas' artillery forces. IDF sources believe Siam was killed in the attack.
Meanwhile, Palestinians reported at least 18 people were killed in IDF attacks early Tuesday morning in the Strip. Three Palestinians were killed in an attack on a building in Jabaliya, and five others were killed in two separate incidents in the Zeitun neighborhood in Gaza City.
Another 10 Palestinians were reportedly killed in the town of Deir al-Balah in the central Strip and in the al-Bureij refugee camp. Among the dead were a father and his three children.
The IDF did not comment on the Palestinians' reports.
On Thursday, Hamas official Nizar Rayyan was killed in an IDF air strike on his house in the northern Strip. The house was destroyed and military officials confirmed that Rayyan was killed.
According to reports, Rayyan's four wives, seven of his children and five other Palestinians were also killed in the strike. Rayyan is considered the highest ranking Hamas official to be assassinated by Israel since Abdel Aziz Rantisi.
