Iran’s Guardian Council approved a bill on Wednesday that would increase uranium enrichment and stop UN inspections of nuclear sites, measures that go against the 2015 nuclear deal, if sanctions are not eased against Iran within two months.

The new bill comes from the Iran parliament after the killing of nuclear scientist Mohsen Fakhrizadeh. Iran blames Israel for the killing.

European parties to the nuclear deal will have two months to ease sanctions against Iran’s oil and financial sectors. Otherwise, Iran will up uranium enrichment to 20 percent.

The Guardian Council returned the first draft of the bill for its ambiguity but approved the second draft of the bill.
