Workers began repairing on Monday a monument to A-bomb victims vandalized last week at Peace Memorial Park in hopes it will be presentable for this weekend's memorial ceremony marking the 60th anniversary of the atomic bombing.

Full restoration of the Cenotaph for the A-bomb Victims is expected to take at least a month, but makeshift repairs are scheduled to be completed by Wednesday.

The vandal was recorded on a security camera Tuesday night using a hammer and chisel to damage the monument's epitaph, which is translated as: "Let all the souls here rest in peace, for we shall not repeat the mistake" of waging war.
