LONDON, April 19 (Reuters) - Euro zone bond yields fell

on Friday as investors tried to reduce risk before the weekend

after reports of an Israeli attack on Iranian soil.

Israel launched an attack on Iran on Friday, sources said,

in the latest exchange between the two adversaries, whose

decades of shadow war has broken out into the open and

threatened to drag the region deeper into conflict.

German 10-year bond yields, the benchmark for

the euro zone bloc, fell 3.4 basis points (bps) to 2.46%,

moving away from a more than six-week high touched on Tuesday.

Italy's 10-year yield was lower by 2.1 bps at

3.86%, and the gap between Italian and German bunds

narrowed 0.9 bps to 139 bps, after briefly hitting

144.9, its highest point since early March.

The spread between U.S. 10-year Treasuries and German bunds

narrowed 2 bps to 212 bps, touching its lowest

level in 9 days.
