TOKYO, March 3 — The yen and euro were broadly lower today as the widening Middle East conflict focused attention on countries dependent on energy imports and how central banks may respond to inflation pressures.

The dollar benefited from safe-haven demand as the US and Israeli air war against Iran spilled out into neighbouring countries. The euro steadied after sliding more than 1 per cent as doubts swirled about when oil shipments from the region will be restored.
