Asian markets fell and oil prices extended gains Friday on worries that an expected ground invasion of Gaza by Israel will spark a wider conflict in the Middle East.

Risk aversion was compounded by US Federal Reserve boss Jerome Powell, who indicated a pause in interest rates at the bank's next meeting but left open the prospect of a later hike.

Traders are keeping a fearful eye on developments in the Middle East.

Hamas militants stormed into Israel from the Gaza Strip on October 7, and killed at least 1,400 people, mostly civilians who were shot, mutilated or burnt to death on the first day of the raid, according to Israeli officials. Israel says around 1,500 Hamas fighters were killed in clashes before its army regained control of the area under attack.

At least 3,785 Palestinians, mainly civilians, have been killed across the Gaza Strip in relentless Israeli bombardments in retaliation for the attacks by the Palestinian Islamist militant group, according to the latest toll from the Hamas-run health ministry in Gaza.

Iran has warned it could be drawn into the conflict if Israel embarks on a land offensive, fanning fears that the region could be embroiled in a wider conflict, with several observers saying such a scenario is becoming increasingly likely.

In a sign that regional players were becoming involved, the Pentagon said a US Navy ship in the Red Sea on Thursday shot down missiles and drones that had been fired by Iran-backed Huthi rebels in Yemen, possibly at Israel.

The likelihood of a Middle East war has sent oil prices surging and both contracts extended the week's gains Friday.

"The risk premium in crude has shot up again," said Vandana Hari, of Vanda Insights.

"As long as the Israel-Hamas tensions run high, crude will remain susceptible to further spikes on signs of an escalation."

Traders are also wrestling with the prospect that US interest rates will remain elevated for some time as the Fed battles to contain inflation.

On Thursday, Powell suggested decision-makers would not hike at their next meeting at the end of October but left the door open to more tightening down the line.

News that weekly jobless claims in the United States came in lower than expected, suggesting the labour market was tighter than many predicted, dealt a blow to traders' confidence.

"Inflation is still too high, and a few months of good data are only the beginning of what it will take to build confidence that inflation is moving down sustainably toward our goal," Powell told a conference in New York.

Additional evidence of "persistently above-trend growth" or fresh signs of tightness in the labour market "could warrant further tightening of monetary policy".

His comments echoed those of his colleagues on the policy board in recent weeks, with a focus on incoming data.

The yield on the 10-year US Treasury note, seen as a proxy for US interest rates, rose above five percent for the first time since 2007.

"Anyone expecting to hear... Powell adopt a less hawkish tone given the recent rise in yields was in for a disappointment, when he indicated that despite recent moves in rates financial conditions probably still weren't tight enough given the continued strength of the US economy," said CMC Markets analyst Michael Hewson.

That weighed on US markets, with all three main indexes losing between 0.8 and one percent.

Asia followed suit, with Tokyo, Hong Kong, Shanghai, Singapore, Taipei and Mumbai all in the red.

Sydney, Seoul, Manila, Bangkok and Wellington were all more than one percent lower.

London, Paris and Frankfurt also fell.

Gold, a go-to safe haven asset in times of uncertainty, extended gains towards the $2,000 mark not seen since the end of July.
