Happy Entry Into Force Day, world! It's been 3⃣ years since the #TPNW's #EIF, we've seen 2⃣ meetings of states parties, and here's 1⃣ take on the #nuclearban treaty's accomplishments in its journey so far.

ICAN @nuclearban Jan 22, 2024

3..2..1.. Nuclear Weapons are illegal!🙌

3 years ago today, the #NuclearBan Treaty entered into force and now we have a treaty that gives us a clear path to eliminate the threat of nuclear weapons use.

This week's #UNGA joint First-Sixth Committee side event, on the legacy of the 1996 ICJ Advisory Opinion on legality of the threat or use of nuclear weapons, was a great opportunity to reflect on the decision's impact, 30 years on, and how the facts and law have evolved since.

ICYMI: on Tuesday, Tonga became the 100th party/signatory to the Treaty on the Prohibition of Nuclear Weapons (#TPNW), depositing its instrument of accession at UNHQ. 👏🇹🇴🙏🇺🇳
Tonga acceded on the 9th anniversary of the TPNW's adoption. And it ratified the #CTBT simultaneously.

Advancing #nuclearban progress, despite increasing global risks and challenges, but also, of course, because of increasing global risks and challenges:

1/ Although we were disappointed by the proceedings of last week’s #NPTPrepCom, and its non-outcome, we managed to hold a number of promising meetings on the sidelines, including relating to the Treaty on the Prohibiton of Nuclear Weapons.
More #NuclearBan moments in the thread🧵
