Helsinki: On Thursday, about 27 young people—mostly children—were hurt in Finland when they fell five metres onto a road following the collapse of a temporary footbridge close to a construction site.

The incident happened in Espoo, close to the capital Helsinki, at around 9:20 am (0620 GMT), when wooden planks gave way and the group fell onto the carriageway of a narrow side road.

According to city officials, the majority of those hurt were eighth-graders, who were on a field trip to an art museum, and were either 14 or 15 years old. One of those hurt was their teacher.

According to Kalle Ristola, fire chief at Western Uusimaa Rescue Department, "We did not have to rescue anyone from immediate danger."

Living on the fifth floor of a building close to the accident scene, Jaakko Markkula told AFP, "I saw the bridge was no longer up and many people (were) on the ground."

In less than five minutes, the first of the 14 ambulances sent reached the scene.

24 patients were transported to various hospitals in the Helsinki area. The majority of the patients had limb fractures, said Helsinki's hospital service HUS, adding that none of the injuries were life-threatening.

HUS medical director Eero Hirvensalo told reporters, "There are some head injuries involved, but there has been no indication of any risk of paralysis."

The footbridge's sides were unharmed, but there was a gaping hole across half of it, with a jumbled pile of wooden planks at one end, according to an AFP reporter who was on the scene.

Soon after the collision, rescue personnel could be seen tending to numerous victims who were lying on the road. According to the Espoo city authorities, the cause of the collapse has not been determined but is still being looked into.
