Anakapalle (Andhra Pradesh), Aug 21 (Reporter) At least ten workers were killed and over 30 others suffered burn injuries in a reactor explosion at a Pharmaceutical Company in Atchutapuram Special Economic Zone (SEZ) in this district on Wednesday.

Some workers might have been trapped in the debris. Over 200 workers are working in the pharma company when the incident occurred.
