Russian and Syrian warplanes have suspended air strikes in the Syrian city of Aleppo ahead of a humanitarian pause on Thursday, Russia has said.
Mr Shoigu urged rebels and civilians in the besieged eastern area of the city to use humanitarian corridors to leave.
Russian warplanes pounded the rebel-held areas of Aleppo shortly before announcing Tuesday's suspension, activists say.
A couple and their three children were killed in the overnight bombing, according to the UK-based Syrian Observatory for Human Rights, a monitoring group.
More than 430 people have been killed in the recent bombardment of rebel areas, it says.
UN agencies have criticised the planned length of Thursday's humanitarian pause, saying at least 12 hours will be needed for people to safely leave the besieged area.
"We would welcome any pause in the fighting, but there is a need for a longer pause in order to get the aid in," said UN spokesman Stephane Dujarric.
