Israel launched strikes on Wednesday after dozens of rockets were fired into Israeli territory by Hamas.

Several people in Israel have been hurt by the rocket attacks, local media say.

The Gaza Health Ministry say pregnant 23-year-old Enas Khammash and her 18-month daughter were killed in Jafarawi in central Gaza.

Her husband was reportedly injured.

A Hamas militant was also killed in one of the strikes, while at least 12 people in Gaza were reportedly injured, health officials said.

Israel has not commented on the reported casualties in Gaza yet.

The Israel Defense Forces (IDF) said the violence broke out after militants shot at an IDF vehicle in Gaza on Wednesday.

After Israel responded with tank fire, dozens of rockets were sent toward Israeli territory on Wednesday night.

Hamas's military wing said it was behind the rocket attacks. Earlier this week two of its militants were killed after Israel shelled a Hamas border post in northern Gaza.

The Israel Defense Forces Twitter account said its fighter jets had targeted more 140 strategic sites, including a weapons manufacturing and storage facility.

"The Israeli strike was conducted in response to the rockets launched from the Gaza Strip at Israeli territory over the course of the evening and night," it said.
