The 30th session of the OPCW Conference of States Parties is underway in The Hague from November 24 to 28.
"The Israeli regime must be compelled to accede to the convention and to submit to full-scope inspections as a priority for the OPCW," Araghchi said during the session.
Israel has not joined any disarmament treaties, including the CWC, and remains the "only obstacle" to creating a WMD-free zone in the region, the Iranian foreign minister said.
While WMDs are inherently dangerous and inhumane, their possession by "wanted criminals" responsible for "massacre and genocide over the past two years" poses a grave existential threat to humanity and the planet, he said.
Araghchi said that the CWC is the most successful disarmament treaty to date but warned that its effectiveness depends on full compliance by all states without exception.
