Santiago, Feb 28 (IANS/EFE): Two masked people set off fire bombs Monday at two bank branches in Santiago, causing damage but no injuries, Chilean police said.

A Banco Santander office and a Bancostado branch in Ñunoa, a Santiago suburb, were attacked.

Security cameras captured images of two masked individuals planting a bomb at the Banco Santander ATM, which was completely destroyed, Carabineros militarized police force Capt. Cristian Acevedo told reporters.

"A search of the sector was conducted and no pamphlets or situations pointing to a specific group have been found," Acevedo said.

The Bancostado branch sustained "great damage to the main inner door, the structure of the ceiling and the building's windows", Acevedo said.

More than two dozen bombings have been staged in Chile since 2006, targeting banks, large corporations, churches and public buildings.

In November, the trial of half a dozen suspects accused of setting off 20 bombs between 2006 and 2010 started at the Justice Center in Santiago.

Responsibility for the blasts is usually claimed by anarchists or anti-globalization groups.
