Firefighting water tankers and military vehicles from across the nation were mobilized Thursday to supply water to South Gyeongsang Province as a deepening drought grips the nation's southeast.

Fire authorities deployed 200 water tankers and some 400 personnel nationwide to deliver water to the province under a national firefighting mobilization order issued Tuesday, according to the South Gyeongsang firefighting headquarters.

An additional 14 vehicles from the Army, Air Force, Navy and the forestry service joined the effort to supply water to farms and households across the drought-hit area.

As of 6 p.m. Wednesday, fire authorities had delivered nearly 4,770 tons of water to the province.
