The local share market has dropped after Iran's reprisal drone strike on Israel, raising fears the conflict could spiral into a broader regional war.
The benchmark S&P/ASX200 index on Monday dropped 35.6 points, or 0.46 per cent, to a nearly four-week low of 7,752.5, while the broader All Ordinaries fell 40.8 points, or 0.51 per cent, to 8,009.4.
The United States was urging Israel to show restraint after Iran fired hundreds of missiles and drones against the Jewish state over the weekend.
Most of the barrage was intercepted but a seven-year-old girl was gravely wounded in Iran's first-ever direct assault on Israel, a retaliation for Israel's April 1 strike on Iran's consulate in Syria that killed seven Iranian officials.
"Everything has temporarily been placed on hold as the markets wake up and work out the risk of war in the Middle East," wrote Capital.com analyst Kyle Rodda.
But the futures market was pointing to a positive open on Wall Street following Friday's plunge, an indication of relief that the attack wasn't worse and had yet to escalate, Mr Rodda added.
