Iran’s retaliatory ‘revenge’ attacks show Tehran still has the firepower to hit back at Israel and U.S. assets in the region.

Attention will shift to central banks on Wednesday, with the Federal Reserve decision later today — with markets pricing in a near-zero chance of a rate cut.

Iran unleashed a flurry of retaliatory attacks against U.S. assets in the Middle East and Israel on Wednesday, vowing ‘revenge’ for the killing of the country’s security chief Ali Larijani, as the weeks-long conflict shows no signs of abating.

Iran’s Islamic Revolutionary Guard Corps said Wednesday that its missiles have hit more than 100 military and security targets in the heart of Israeli territories, while Tehran also launched several explosive drones at the U.S. embassy in Baghdad.
