Indonesia quake spurs rush to high ground.

PADANG, Indonesia, Sunday (Reuters) An earthquake of magnitude 6.8 rattled parts of Indonesia on Sunday, sending people in this city on Sumatra island rushing out of their homes and heading toward high ground in fear of a possible tsunami.

However, there were no immediate reports of casualties or damage, or that the quake had actually caused a tsunami, officials in Jakarta said.

According to the U.S. National Oceanic and Atmospheric Administration, no tsunami warning has been issued as a result of the quake, but it also said there are no tsunami detection devices in the immediate area of the quake.

The latest quake was felt in Indonesia's neighbour Singapore as well.
