At least 10 people received medical treatment, with two hospitalised, after a major fire on Saturday disrupted production at a key Tata Electronics plant in southern India which makes Apple iPhone components.

A forensic investigation is now underway into the fire, that broke out at Tata Electronics' Hosur factory in Tamil Nadu on Saturday. The factory, which makes components for Apple iPhones, was badly hit by the fire.

The fire marked another significant disruption for Apple’s supply chain in India, where the tech giant has been steadily increasing its manufacturing presence.
