NEW YORK, Oct. 3 (Xinhua) - Death toll exceeded 200 on Thursday in hurricane-stricken southeastern U.S. states, according to NBC News.

At least 204 people are known to have died across six states as a result of the destruction wrought by Hurricane Helene since it made landfall in Florida a week ago, reported the news outlet, adding that hundreds are still missing and nearly a million customers remain without power.

Helene has become the deadliest hurricane to strike the U.S. mainland since Hurricane Katrina in 2005.

More than half of the fatalities were confirmed in storm-ravaged North Carolina, with at least 98 deaths. In particular, Buncombe County, which located in western North Carolina, reported 61 deaths.

U.S. President Joe Biden decided Wednesday to immediately deploy "up to 1,000 active-duty soldiers to support the delivery of food, water and other critical commodities to communities affected by Hurricane Helene."

The active-duty military personnel are in addition to more than 1,000 North Carolina National Guard soldiers currently deployed, who are surging food, water, supplies and conducting search and rescue operations, according to North Carolina Governor Roy Cooper.

The governor noted on Thursday that "around-the-clock efforts continue to provide resources and assistance" to communities in western part of the state.

Biden toured the Carolinas to survey damage on Wednesday and is scheduled to visit Florida and Georgia on Thursday. The White House said in a news release that Biden will further survey damage caused by Helene and meet with state and local leaders regarding ongoing response efforts.

"The president and his entire administration will continue to do everything in our power to help the people of Florida, Georgia, and every community affected by this storm," said the White House.
