The shooting occurred in Hwacheon, some 90km (56 miles) north-east of the South’s capital, Seoul.
Lee Jong-joo, of the South Korean Unification Ministry, told Agence France-Presse news agency: “The reunions will go ahead as scheduled despite the firing.”
North and South Korea are holding another round of reunions of families split by the countries’ war in the 1950s.
For a three-day reunion with relatives, more than 400 South Koreans were bussed over the border.
The reunions will take place at the Mount Kumgang resort.
These are the first meetings since the South accused the North of sinking one of its warships in March.
97 South Korean families were involved in the latest reunions. They will meet the same number of North Korean families.
In the 70s, Lee Moon-yeong told AFP he was meeting a brother he thought might have been killed in the Korean War.
A second set of reunions is set for Wednesday-Friday at the same venue, involving 96 South Koreans and 207 North Koreans.
The last reunions were held in October 2009.
Since March, tensions have been high between the two rivals. The South accused the North of torpedoing one of its warships, killing 46 people. Pyongyang denies the charge.
The chaos of the 1950-53 saw millions of people separated from their families. And since at the end of the conflict there was an armistice but no peace treaty was signed, technically the North and South are still at war.
Brief reunions for about 20,000 families have been permitted since a landmark inter-Korean summit in 2000, but the Red Cross-brokered programme has been a hostage of the fluctuating relations between North and South.
And time is running out for many families. According to South Korean officials, up to 4,000 people on the waiting list die each year.
