LONDON, April 4 (Reuters) - The euro fell on Monday as Western powers said new sanctions were needed against Russia following civilian killings in Ukraine that appeared to amount to war crimes.
The euro, which has been under pressure due to worries about the economic damage from the war in Ukraine, slipped 0.4% versus the dollar to park to $1.1005 at 1120 GMT. Against sterling, it fell to a six-day low and it was last down 0.3% at 84.01 pence.

The Kremlin denied any accusations related to the murder of civilians in the town.
German Defence Minister Christine Lambrecht said the European Union should discuss ending Russian gas imports. Russia supplies some 40% of Europe's gas needs.

"In my view the risk of significant euro weakness increases."

Speculators' net long bets on the dollar rose to an 11-week high in the latest week.
Fed funds futures have priced a near 4/5 chance of a 50 basis point hike next month, while two-year U.S. yields climbed to their highest level since March 2019.
