Air strikes by Israel's military on the Gaza border have killed three people including a pregnant woman and her toddler, the Gaza Health Ministry says, BBC reports.
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.
