PRECIOUS-Gold steady, North Korea worries support

* Equities slip as N.Korea claims Trump tweet 'declaration of war'

* Markets await Fed Yellen's speech at 1645 GMT

* Spot gold may test support at $1,252/oz in 3 months- technicals

(Updates prices, adds analyst comments) Sept 26 (Reuters) - Gold held steady on Tuesday after rising over one percent in the previous session, supported by safe-haven demand amid rising tensions surrounding North Korea and as the dollar eased from near three-week highs.

Spot gold was nearly unchanged at $1,310.61 per ounce

at 0339 GMT, not far from Monday's high of $1,311.50, when it marked its biggest intra-day percentage gain since Sept. 7.

U.S. gold futures for December delivery rose 0.2

percent to $1,314.30 per ounce. "The sharp sell-out in the equity market and rising risk aversion (are driving gold prices)," said Richard Xu, a fund manager at China's biggest gold exchange-traded fund, HuaAn Gold. North Korea's foreign minister said on Monday that a weekend tweet by President Donald Trump counted as a declaration of war on North Korea and that Pyongyang reserved the right to take countermeasures, including shooting down U.S. bombers even if they are not in its air space "Gold will continue to be headline-driven in the short term," said Jeffrey Halley, a senior market analyst with OANDA. Asian shares slumped on Tuesday while the dollar remained off recent highs against the yen against the backdrop of rising tensions on the Korean Peninsula. Investors also awaited a speech on "inflation, uncertainty, and monetary policy" by U.S. Federal Reserve Chair Janet Yellen, in Cleveland at 1645 GMT. "Chinese real estate developers getting hit pretty badly (on Monday) because of the curbing of property sales and the downgrade of China's sovereign rating are also causing people to rethink their risky positions," Xu said. China and Hong Kong shares fell on Monday, led by property stocks after some cities imposed new housing controls to hose down an overheated market. Monday's weak performance followed a hawkish Federal Reserve policy statement last week and Standard & Poor's downgrade of China's sovereign credit rating. Spot gold may test a support at $1,252 in three months, a break below which could trigger a further drop towards the next support at $1,174, Reuters technical analyst Wang Tao said.

In other precious metals, silver was up 0.1 percent

at $17.19 per ounce. In the previous session, prices rose over 1 percent to register their biggest intra-day percentage gain since Sept. 7.

Platinum gained 0.1 percent to $939.50 per ounce

after also registering its biggest intra-day percentage gain since Sept. 7 in the previous session.

Palladium rose 0.5 percent to $914.70 per ounce.
