At least six masked attackers stormed the Frankfurt Stock Exchange Wednesday, beating employees and throwing firebombs onto the main trading floor, authorities said. Two people were injured.

A police spokesman said the attack, carried out before trading began, apparently was intended to draw attention to a nationwide prison hunger strike by members and sympathizers of the terrorist Red Army Faction. Three suspects were captured.The attackers forced their way onto the main floor of the stock exchange by beating up a guard posted at the entrance to the building. The attackers began throwing the firebombs as employees were preparing for the start of trading, the spokesman said.

Six to eight people took part in the "coordinated" attack on the exchange and three people were arrested, the police spokesman said. The other attackers escaped, he said.
