BEIJING - Communication services have resumed in China's quake-hit region after rescue work overnight, China's three telecommunication operators said on Wednesday.

China Telecom, China Mobile and China United Telecom, have launched emergency programs to restore communication signals in Jinggu County of southwest China's Yunnan Province, after the area was hit by a 6.6-magnitude quake at 9:49 pm Beijing Time on Tuesday.

They opened hotlines to help victims looking for relatives.

The quake has killed at least one and left 324 people injured and forced 124,6000 people from their homes by Wednesday morning.

It's the second strong quake to hit the province in two months. A 6.5-magnitude quake struck Ludian county on Aug 3, killing at least 615 people.
