LONDON (Reuters) - Hackers working for the Chinese government have broken into telecoms networks to track Uighur travellers in Central and Southeast Asia, two intelligence officials and two security consultants who investigated the attacks told Reuters.

The hacks are part of a wider cyber-espionage campaign targeting "high-value individuals" such as diplomats and foreign military personnel, the sources said. But China has also prioritised tracking the movements of ethnic Uighurs, a minority mostly Muslim group considered a security threat by Beijing.
