One person has been killed and another injured in a huge explosion that has ripped through a university chemistry department in eastern France.
The blast was followed by a fire at the university in the town of Mulhouse, on the River Rhine.
Rescue workers faced thick smoke when they arrived at the ENSCMu institute of chemistry on the university campus.
The reason for the blast, which was heard across much of the city close to the Swiss and German borders, was not immediately known. The institute has some 650 students and staff.
However, the UNEF student union said the complex was not occupied by students as most are taking part in the protests against a youth jobs law that have hit universities around France.
