UN Secretary-General Antonio Guterres on Saturday called for concerted global efforts to deal with the challenge of the use of new technologies by various terror groups to radicalise people and foment discord in societies.

In a message at the UN Security Council Counter-Terrorism Committee's meeting in Delhi, he expressed concerns over the abuse of new technologies by various terror groups to spread disinformation, foment discord and radicalise youths.

The counter-terror meeting in Delhi is being attended by representatives from all 15 member nations of the UN Security Council.

The message by Guterres was read out by an official of the global body.

"New and emerging technologies have unmatched potential to improve the human conditions everywhere, regrettably they have been also been misused by many including malicious actors," the UN Secretary-General said.

"Terrorists and others posing hateful ideologies are abusing new and emerging technologies to spread disinformation, foment discord, recruit and radicalise, mobilise resources and execute attacks," he said.

Guterres said the COVID-19 pandemic has highlighted many vulnerabilities to such misuse.

"We must adopt concrete measures to reduce these vulnerabilities while committing to protect all human rights in the digital sphere," he said.

"This can only be achieved through effective multilateralism and international cooperation anchoring our responses in the values and obligations of the UN charter and the universal declaration of human rights," he added.

India's Permanent Representative to UN Ruchira Kamboj said the new and emerging technologies have helped fuel economic growth but they have also thrown up challenges which need the attention of the international community.

Kamboj is chairing the meeting.

She said the use of new technology to carry out terrorist activities is increasing.

"The use of new and emerging technologies for terrorist purposes is increasing, diversifying and evolving as varied technologies become cheaper and more readily available," she said.

Besides representatives of UN Security Council member countries, the meeting is being attended by global experts and leading agencies with an aim to discuss threats posed by the use of technologies for terrorist purposes.

The first day's meeting took place in Mumbai on Friday.

It is for the first time that the UN Security Council is holding a meeting, in any format, in India.
