A bus in northern China has fallen off an expressway into a ditch, killing 26 people.

The government in the port city of Tianjin says the crash happened Friday night after a tire burst.

It says the bus was carrying 30 people.

The official Xinhua News Agency reported that the four others on board were found alive by early Saturday.

Xinhua says the long-distance bus plunged off the Tianjin-Jixian expressway at the Baodi section.
