In a letter to UN Secretary General Antonio Guterres, Iran's Ambassador to the United Nations Majid Takht Ravanchi said that as admitted by the group, it has carried out several terrorist attacks in the country that killed or injured a number of civilians, IRNA reported.
However, the group is still conducting its acts of terror from inside the United States and is even training terrorists to carry out acts of sabotage in Iran, he added.
He emphasized that Iran has on numerous occasions informed the United States of the group's terrorist crimes through the Swiss Embassy in Tehran, which represents the US’ interests section, but Washington has so far carried out no measure to prevent acts of terror by the group's members or extradite them to Iran for trial.
Based on the international law, countries are committed not to support terrorists and allow them to use their soil for terrorist acts against other states, Takht Ravanchi said.
The Iranian envoy added that the continuation of the US support for the Tondar group leaves no doubt that Washington is blatantly violating all its international obligations and therefore is liable for all criminal acts committed by the group's members in Iran.
The Iranian Intelligence Ministry said on August 1 that it had arrested Jamshid Sharmahd, the ringleader of the Tondar terrorist group.
