A “human error” was the cause of a deadly train crash that killed at least 14 passengers and injured nearly 50 in India’s southeastern Andhra Pradesh state, officials have said.

A passenger train overshot a signal on Sunday between the towns of Alamanda and Kantakapalle in the Vizianagaram district, striking a stationary train. At least three cars were derailed in the accident, Saurabh Prasad, a senior railway officer, said.
