A four-year-old girl has died after being shot by her three-year-old sister after she got hold of a loaded semi-automatic pistol.
The two sisters were home in an apartment with five adults, including their mum and stepdad, but each one thought another was looking after the girls, local Sheriff Ed Gonzalez said.
The tragic incident, which is believed to have been an accident, happened at an apartment block in Harris County, Texas, not far from Houston, US.
