Four escaped chimpanzees are still on the loose after three others were shot dead during a breakout at a Swedish zoo.

Seven primates fled their enclosure at Furuvik Zoo on Wednesday, but on Thursday Swedish officials said one wounded animal has not received veterinary attention because no one could get inside the building at the zoo safely.

The chimps are inside the monkey house, but the staff have not been able to get the three uninjured ones back into their enclosure, the animal park management said in a statement. The wounded animal returned to its enclosure on its own.
