KARACHI, Oct 29 (Reuters) - More than 100 people were killed when a strong earthquake struck southwestern Pakistan on Wednesday bringing down hundreds of houses, and the toll was expected to rise, a provincial government minister said.

"More than 100 people have been killed and the death toll is expected to rise," said Provincial Revenue Minister Zamrak Khan.

"Eight villages in Ziarat have been badly affected and there are still many areas which have not yet been reached," Khan told Reuters.

Ziarat is a scenic valley, one of Baluchistan province's main tourist spots, 70 km (45 miles) northeast of the provincial capital, Quetta. (Reporting by Gul Yousafzai; writing by Robert Birsel; editing by Roger Crabb)
