Samsung is yet to comment on reports it's suspended production of its new Galaxy Note 7 smartphone - after replacement devices caught fire.

The model was withdrawn from 10 countries last month because of faulty batteries, causing some of the phones to go up in flames.

Reuters and South Korea's Yonhap news agency cited unnamed officials claiming the company had temporarily halted its Galaxy Note 7 production lines.

The move came as two US networks stopped replacing or selling the phone.

The South Korean firm issued a recall of the smartphone in September and assured customers last month that the fixed devices were safe.
