The blasts came during a Farmers Day celebration at an outdoor stadium that was attended by nearly 1,000 people.
Two explosions went off at a celebration in a stadium in the Afghan city of Lashkar Gah on Saturday, killing four people and wounding 31, government officials said.
The blasts came during a Farmers Day celebration in the southern city that was attended by nearly 1,000 people.
The governor of Helmand province, Mohammad Yasin Khan, was knocked over by the blasts, but suffered only superficial injuries, a spokesman said.
The blasts appeared to have been caused by planted explosives. There was no immediate claim of responsibility.
The attack is one of several to occur during Afghanistan's multi-day celebrations to mark its traditional new year, beginning with explosions in the capital of Kabul on Thursday.
Those attacks killed six people and wounded 23 and were claimed by Islamic State.
The traditional new year is widely celebrated in Afghanistan but some hardline Islamists oppose the festivities, saying they are un-Islamic.
Helmand, a source of much of Afghanistan's opium, is one of several Afghan provinces in which insurgents have the greatest control and influence. Lashkar Gah is the provincial capital.
Saturday's attack came exactly one year after a car bomb killed at least 14 people who had gathered to watch a wrestling match in Lashkar Gah.
Fighting has been relentless in Afghanistan amid recurring peace talks between US and Taliban negotiators. The latest negotiating round wrapped up this month with both sides saying there was progress toward ending the 17-year war.
The US Special Inspector General for Afghanistan Reconstruction estimated in January that the government controlled or influenced just over half the country, covering nearly two-thirds of the population.
