One person was killed and six others - including three pregnant women - were wounded Monday when armed men tried to steal an armored car at a bank in suburban Buenos Aires, Argentine authorities said.

The fatality was identified as a 75-year-old man.

Also injured besides the expectant mothers, who are out of danger, was another woman and two security guards of the armored car company, one of whom is in critical condition.

Of the three pregnant women, only the one with a wound in her thigh is still hospitalized "as a precaution," the deputy health minister in Buenos Aires province, Sergio Alejandre, said in a communique.

"The other two and a 54-year-old woman, with scrapes on her right leg and foot, were released from hospital," the deputy minister said.

The incident occurred in the early hours Monday at the door to the downtown Supervielle bank branch in Moreno municipality, some 42 kilometers (26 miles) from the Argentine capital.

The robbers attacked the security guards when they parked the armored car at the bank entrance, which sparked the shootout.

Though the criminals managed to escape, one of them is known to be wounded from the blood found inside the SUV in which they escaped, and which they later abandoned several blocks away. EFE
