A woman killed and over 30 persons were injured when an old iron bridge across a water-body and connecting two units of the state-owned Kerala Minerals and Metals Ltd (KMML) collapsed on Monday, police said.

The incident occurred around 10:45am when mostly KMML workers were using the bridge. The deceased is Shyamala Devi.

The bridge had been waiting for major repair for a long time, locals said.

Those crossing the bridge were injured as iron rods fell on them.

‘Those who have been injured were immediately moved to a government hospital while some were taken to private hospitals,’ said a person helping with the rescue operations.
