The woman who was killed on Thursday, when a rocket hit a home in Rehovot, was identified on Friday evening as Inga Avramian, in her 80s.
16 other people were injured in the attack.
IDF spokesperson Daniel Hagari said on Friday morning that the direct hit on the building occurred due to a technical malfunction of the Iron Dome missile defense system. While an interceptor missile was fired at the rocket, the missile failed to hit its target.
The rocket that hit the building is intended for ranges of about 70 kilometers (44 miles) and carries approximately 20 kilograms (44 pounds) of explosive material.
"We understand that an interceptor was launched and missed," said Hagari. "It is a homemade rocket and not an advanced rocket. It is a rocket with a range of about 70 kilometers and bearing 20 kilograms of explosive material, which hit at an angle on a building."
