Palestinian media says Israeli aircraft and artillery struck Gaza’s southern city of Khan Younis in at least two waves and 15 people were killed. Attacks were also reported in several other parts of Gaza, including the Jabalia and Nuseirat camps.

There was no immediate comment from Israel and Reuters was unable to independently verify the reports.

In Israel, sirens warning of incoming rocket fire from Gaza blared in communities near the border with the enclave, the military said. There were no reports of damage or injuries.
