Israeli airstrikes and tank fire killed at least four Palestinians across Gaza on Monday, including two children, hospital officials said.

In Khan Younis, relatives gathered to mourn a 10-year-old girl killed by tank fire. A 4-year-old boy was killed in a separate strike on a building in the Bureij refugee camp.

The Israeli military said it was not aware of the incident involving the girl and did not comment on the Bureij strike.
