OCCUPIED JERUSALEM: An Israeli official on Sunday dismissed as "nonsense" an allegation by the Iranian foreign minister that Israel was trying to trick the United States into waging war on Iran.

It was Israel that needed to be on alert for possible Iranian strikes on the one-year anniversary on Sunday of the assassination of Tehran's top general, Qassem Soleimani, in a US drone strike in Iraq, Energy Minister Yuval Steinitz said on Kan public radio.

Washington blames Iran-backed militia for regular rocket attacks on US facilities in Iraq, including near the US embassy. No known Iran-backed groups have claimed responsibility. On Saturday, Iranian Foreign Minister Mohammad Javad Zarif said on Twitter: "New intelligence from Iraq indicate that Israeli agent-provocateurs are plotting attacks against Americans - putting an outgoing (President Donald) Trump in a bind with a fake casus belli."

"Be careful of a trap, @realDonaldTrump. Any fireworks will backfire badly, particularly against your same BFFs," Zarif wrote, in what appeared to be a veiled threat against Israel.

Steinitz said the remarks showed that Iran, after mounting US sanctions billed as curbing its nuclear programme and involvement in regional conflict-zones, was "under pressure - economic pressure, and pressure in terms of national security".
