The search for a 13 year old boy who on Saturday went missing in the waters of the Danube river near the Bulgarian city of Silsitra.
In the early afternoon, the Border Police boat will return for another search in the area.
The Romanian border authorities will also assist.
The boy, together with friends, was seen jumping off into the river from a helicopter landing near the bank, despite the swimming bans. The place is considered as one of the most dangerous sections of the river in the area and therefore swimming is banned.
