Iran’s Foreign Ministry spokesman says that officials in the Islamic Republic plan to meet Sunday night to discuss their next step out of the nuclear deal and that it will be even bigger than initially planned.

Abbas Mousavi makes the comment Sunday during a briefing with journalists after a US airstrike killed Iranian Revolutionary Guard Gen. Qassem Soleimani.

Mousavi says the step would be greater than planned as “in the world of politics, all developments are interconnected.”

If taken, it would be the fifth step to break terms of Tehran’s 2015 nuclear deal with world powers, which saw Iran limit its enrichment of uranium in exchange for the lifting of economic sanctions.

Mousavi does not elaborate on what that step could be. Iran previously has broken limits of its enrichment, its stockpiles and its centrifuges, as well as restarted enrichment at an underground facility.
