The US broadened the scope of its sanctions on Iran’s oil and gas sectors in response to a ballistic-missile attack on Israel, ramping up economic pressure on Tehran ahead of Israeli retaliation that’s expected any day.

• The Treasury Department invoked a Trump administration-era executive order that allowed for sanctions on any area of the Iranian economy to deny it funding to finance malign activity.
• Recent move essentially declares the country’s petroleum and petrochemical sector off-limits, allowing for sanctions on anyone linked to it.
•  Israel is expected to launch on Iran at any time in retaliation for a ballistic-missile barrage that struck but caused limited damage to Israeli targets on Oct. 1.
• The US has pressed Israel not to target Iran’s energy sector or nuclear sites for fear of escalation and of global economic fallout.
• Instead, US officials offered to impose fresh economic sanctions, people familiar with the matter have said, and Friday’s action may be the result.
