FOREX-Yen at 10-day low vs dlr after Ukraine talks, U.S. data
* Safe-haven bids on yen unwound on hopes for Ukraine initiative
* U.S jobless claims, Philadelphia Fed survey point to upswing
* Euro capped as ECB officials warn against its strength
* Many markets closed on Friday for Easter holiday
TOKYO, April 18 (Reuters) - The yen slipped to 10-day lows against the dollar on Friday after speculators unwound some safe-haven trades following upbeat U.S. economic data and on hopes for a diplomatic initiative seeking an end to violence in Ukraine.
The dollar traded at 102.43 yen, and has ticked up in the past five sessions from a three-week low of 101.32 yen.
Worries about tensions in the Ukraine, which have prompted some safe-haven buying of the yen, eased somewhat on Thursday after the United States, Russia, Ukraine and the European Union called for an immediate halt to violence.
Further, U.S. data pointed to activity regaining momentum after disruptions due to harsh winter weather.
New claims for jobless benefits hovered near their pre-recession levels last week and manufacturing in the Mid-Atlantic region accelerated in April.
"There are signs of a pick-up in the U.S. economy markets have been long waiting for," said Shinichiro Kadota, chief forex strategist at Barclays Bank in Tokyo.
Trading is expected to be subdued on Friday, as many centres are closed for Easter, though Tokyo markets are open.
The dollar has risen above the 38.2 percent retracement of its fall from its April peak of 104.13 yen, with next resistance seen at the 50 percent retracement of 102.73 yen.
The euro was at $1.3815, little changed over the past few sessions. It hit a 2-1/2 year high near $1.40 last month, and since then European Central Bank officials have tried to talk it down given concerns that a strong currency could derail the euro zone's fragile economic recovery.
The latest was Executive Board member Yves Mersch, who said a sustained appreciation in the euro would inevitably trigger a reaction from the ECB.
Last weekend, ECB President Mario Draghi identified the euro's strength as a possible trigger for easing policy.
Sterling hit 4 1/2-year high of $1.6842 on Thursday before easing back to $1.6781. Against the euro, the pound stood at 82.27 percent to the euro, near a six-week high of 82.15 hit on Thursday. (Editing by John Mair)
