Tianjin disaster: Travelling into the blast zone

BBC Beijing producer Xinyan Yu was among the first journalists at the scene of the massive explosions which have rocked the Chinese port city of Tianjin.

These are some the images and tweets she has sent back as she travelled into the city - it was a "horrifying" sight, she said.

The BBC team joined dozens of fire engines and military vehicles heading towards Tianjin, about 120km (75 miles) from the capital, Beijing, in the early hours of the morning.

This sheet of metal was twisted and burned, and thrown into the street by the force of the blast.
