The Sri Lanka Twins event at a sports stadium in Colombo had aimed to gather 5,000 pairs of twins to take the record from Taiwan, where 3,961 sets of twins, 27 sets of triplets and four sets of quadruplets gathered in 1999.

They said some of the gathered twins became frustrated with the wait times and left before posing for the mandatory group photo at the end of the event. The group said they will plan another event for next year if they fail to make the record.
