NEW YORK, April 13 (Xinhua) -- The U.S. dollar index climbed slightly on Friday as investors continue to monitor the geopolitical tensions in the Middle East.

The dollar index, which tracks the greenback against six major peers, was up 0.04 percent at 89.783 in late trading.

U.S. President Donald Trump said on Wednesday that Russia should get ready for missile attacks against Syria. He amended the warning on Thursday, saying a military strike "could be very soon or not so soon at all."

Analysts said Trump's latest words lowered market concerns for immediate military clashes and increased market appetite for riskier assets. The greenback rose 0.16 percent against Japanese Yen, a traditional safe-haven currency.

On the economic front, consumer sentiment slipped in early April, largely reversing the gains recorded in the prior two months.

The University of Michigan's mid-month report on consumer attitudes about the economy went down to 97.8 in mid-April, lower than market expectations.

In late New York trading, the euro climbed to 1.2334 dollars from 1.2330 dollars in the previous session, and the British pound increased to 1.4243 dollars from 1.4226 U.S. dollars in the previous session. The Australian dollar was up to 0.7761 dollar from 0.7756 dollar.

The U.S. dollar bought 107.46 Japanese yen, higher than 107.20 Japanese yen of the previous session. The U.S. dollar was up to 0.9622 Swiss franc from 0.9621 Swiss franc, and it rose to 1.2614 Canadian dollars from 1.2587 Canadian dollars. Enditem
