A new treaty seeking international cooperation to prevent acts of nuclear terrorism and bring perpetrators to justice will come into force on July 7, almost two years after it was adopted.
Bangladesh became the 22nd country to ratify the International Convention for Suppression of Acts of Nuclear Terrorism which allows it to enter into force.
United Nations Secretary-General Ban Ki-moon congratulated the States that have already ratified or acceded to the Convention for making it possible for it to enter into force with such speed.
Calling nuclear terrorism "one of the most serious threats of our time," he observed that even one such attack could inflict mass casualties and create immense suffering.
"This prospect," he added, "should compel all of us to prevent such a catastrophe."
Not only will the new Convention thwart terrorists from attaining "the most lethal weapons known to man," but it will be the 13th international instrument on terrorism, bolstering existing global mechanisms against the menace, he said.
The Convention will also promote cooperation among nations, which is key in tackling terrorism.
The Secretary-General appealed to all States to ratify or accede to the treaty "without delay," noting that last September, the General Assembly adopted the UN Global Counter-Terrorism Strategy which also calls for universal adherence to anti-terrorism conventions.
Originally proposed by Russia, the Convention was adopted on April 13, 2005 and 115 countries have signed it.
