Shock and horror at scene of Gaza blast

At least 16 people have been killed in an air strike on a school in the Gaza Strip, Palestinian officials have said.

Dozens more were injured in the attack on the building which was sheltering displaced people at Nuseirat refugee camp in central Gaza, according to the Hamas-run health ministry.

Video from the scene shows adults and children screaming in a smoke-filled street covered in dust and rubble, as they run to help the wounded.

The Israel Defense Forces (IDF) said it struck several “terrorists operating in structures located in the area of Al-Jaouni School”.

Eyewitnesses told the BBC that the attack targeted the upper floors of the school, which is located near a busy market.

The BBC understands that up to 7,000 people were using the building as shelter.
