German Leftists Set Off Bombs, Denounce Economic Summit

BONN â€”  A West German leftist terrorist group set off three bombs Monday to denounce the seven-nation economic summit conference opening here Thursday, and a senior police official warned that other attacks may follow.

The explosions went off within minutes of one another in the early morning at two office buildings in Cologne, 20 miles from Bonn, and one in Duesseldorf, farther north. No one was injured, but damage was extensive. The targets were the chemical group Hoechst and a railway insurance fund in Cologne and the Deutsche Bank in Dusseldorf.

The Revolutionary Cells claimed responsibility for the bombings in letters to the Cologne newspapers Tageszeitung and Stadtnazeiger. The same group had taken responsibility for three similar attacks two months ago against targets in Hamburg, Essen and Bochum.

The letter said that the attacks were made in retaliation for the “plundering of the Third World� and denounced the forthcoming economic meeting of heads of government of the United States, West Germany, Britain, France, Italy, Canada and Japan.

Massive Security for Summit

Massive security is in force in the Bonn area for the heads of government, who will begin arriving on Wednesday. However, federal criminal police president Heinrich Boge issued a statement from his headquarters in Wiesbaden warning that there might be more terrorist strikes elsewhere in West Germany and in neighboring countries.

Meanwhile, a major behind-the-scenes effort since the 1984 London summit to speed up the exchange of police information on terrorists appeared to have paid off in Paris on Monday. Police announced the arrest of a Turk, arriving on a train from Brussels, who appears to be implicated in the recent wave of bombings against North Atlantic Treaty Organization targets in Belgium.

The Turk, identified as Muzaffar Cacar, 26, is a resident of Strasbourg, a French city on the German border, but he arrived back in Paris carrying false Belgian identity papers and a Belgian driver’s license.

More important, he was also carrying four sticks of dynamite and detonators stolen from a quarry south of Brussels in June, 1984, authorities said. Dynamite was used in failed car-bomb attempts last August outside the Paris headquarters of the Western European Union and in November outside a NATO officers school in Oberammergau in Bavaria.
