BEIJING, June 26 (Xinhua) -- China issued a grade-IV emergency response on Monday following rain, storms and flooding across central China's Hunan Province, which have left six dead and one missing.

The Ministry of Civil Affairs and China National Commission for Disaster Reduction have sent teams to assist in disaster-hit areas.

Since June 22, Hunan has been battered by rain and floods.

By 8 a.m. Monday, six people had died, another one remained missing, and 11,000 had been evacuated to safer places, according to local government.

The disaster also damaged about 40,000 houses, and caused 3.27 billion yuan (479.3 million U.S. dollars) in direct economic losses.
