UPDATE 2-North Korea tensions, strong euro send European shares to six-month low


* STOXX 600 down 1.5 percent

* Euro climbs above $1.20, piling pressure on stocks

* North Korea missile saps demand for riskier assets

* Banks fall to two-month low

* Prosiebensat sinks media sector on advertising worries (adds investor quotes)

LONDON, Aug 29 (Reuters) - Rising geopolitical tensions and a surging euro sent European shares to their lowest in six months on Tuesday after a missile launch by North Korea sapped Asian markets.

The pan-European STOXX 600 fell 1.5 percent, set for its worst daily performance in nearly 14 months and firmly on track to make August its third month of losses in a row.

Political risks and a strengthening currency denting exporters have put pressure on European benchmarks.

On Tuesday the euro surged above $1.20 for the first time since January 2015, after European Central Bank Chief Mario Draghi refrained from talking down the currency which has gained 14 percent year-to-date against the dollar.

The euro effect combined with a broader risk-averse mood to send euro zone stocks and blue-chips down 1.3 percent. Britain's FTSE fell 1.4 percent and the exporter-heavy DAX hit a five-month low.

North Korea fired a missile over northern Japan, weakening Asian stocks and the U.S. dollar overnight.

As geopolitical concerns spread to European markets, all sectors fell. Among the only bright spots were gold miners Randgold Resources and Fresnillo, up 3.1 to 3.8 percent as the price of gold soared to a 9 1/2 month high with investors rushing into safe haven assets.

Banking stocks sank 1.3 percent to a two-month low.

The VSTOXX, a gauge of European investor anxiety, jumped to its highest in a week.

"I think today's correction is more due to the stronger euro, and North Korea is more an excuse or a catalyst," said Angelo Meda, fund manager at Banor SIM.

"Markets are discounting the impact of EUR/USD on European earnings, but as of today it's too early to call for a long-term correction," he added, saying the U.S. market was still supported by low interest rates and good earnings growth.

"We need to monitor the evolution of U.S. politics and macroeconomics in the next weeks to determine if there is the risk of a bear market or if this is just a blip."

German commercial broadcaster Prosiebensat fell as much as 13 percent after flagging a weaker outlook for advertising in the third quarter, the third cut in advertising guidance this year according to Deutsche Bank analysts.

"The most direct negative read-through is for German peer RTL," said analysts at the German bank.

"But this also represents another major piece of evidence of the disconnect between solid European macro trends and weakening TV ad momentum," they added.

RTL Group dropped 8 percent, while Spanish and British broadcasters Mediaset Espana and ITV both also fell 3.5 to 5 percent.

The losses heaped pressure on the media sector, the second worst-performing in Europe this year.

Lundin Petroleum sank 7 percent after its Korpfjell prospect, a joint venture with Statoil in the Arctic Barents Sea, found no oil and only non-commercial quantities of natural gas.

With the Jackson Hole symposium yielding no big change to monetary policy expectations, and an earnings season meeting lukewarm share reactions, catalysts to support European equities were scarce.

Some investors expected a correction, though valuations in the region remained attractive relative to Wall Street.
