More than 100 searchers are scouring an area in Pictou County for 6-year-old Lily Sullivan and 4-year-old Jack Sullivan.

The siblings were last seen Friday morning on Gairloch Road in Lansdowne Station, about 20 kilometres southwest of New Glasgow.

Search and rescue teams along with volunteers continued to look for the children on Saturday. Two helicopters and a drone are also part of the search.

Police say the children are believed to have wandered away from a home in the area.
