Jakarta's Air Force base commander Rear Marshal Dwi Putranto says he was informed on Monday that an Australian Orion aircraft had detected suspicious objects near Nangka island, about 100 miles (160 kilometers) southwest of Pangkalan Bun, near central Kalimantan, or 700 miles (1,120 kilometers) from the location where the plane lost contact.

"However, we cannot be sure whether it is part of the missing AirAsia plane," Putranto says, "We are now moving in that direction, which is in cloudy conditions."
