Nearly 7,000 soldiers will guarantee, starting from Tuesday, public order and the handing over of aid to the victims of Saturday's earthquake, as ordered by Chilean President Michelle Bachelet.

In Concepcion, the country's second city in importante and capital of Bio Bio region, there were sackings and fires on Monday and two strong 6 degrees on the Mercalli scale aftershocks took place early Tuesday morning.

The government announced it has sent aid to that region including five million food portions, 320 tons of aid as water, food, tents, camp beds, energy generators, diapers and chemical toilets.

Director of the National Emergency Office (ONEMI) Carmen Fernandez underlined in her most recent report that the number of quake victims could reach two millions nationwide.

She indicated that the number of dead people is still at 723 and that there are 19 missing and more than 500 injured in El Maule and Bio Bio.

Even though Santiago de Chile is going back to normality, there are still zones with no electricity or water and around 1,500 houses were damaged and at least two schools shut temporarily.

Meanwhile, international solidarity has started to flow into Chile after the arrival on Monday of Brazilian President Luis Inacio Lula Da Silva, who offered a large field hospital for the next days, among other aid.

Bolivian Foreign Minister David Choquehuanca is expected to arrive on Tuesday to Santiago. He will bring 50 tons of drinkable water with him.

Peruvian President Alan Garcia and US Secretary of State Hillary Clinton are also expected to arrive to Chile.
