Majlis Speaker Ali Larijani held separate meetings with counterparts from Syria, Lebanon, Serbia, and Bangladesh on Monday.
After the meetings, he outlined the most prominent issues discussed with the officials, IRNA reported.
He said, "Many countries in the world, particularly Europeans, are concerned about the violent and brutal actions of terrorists in the region and accordingly have made efforts to ratify strict laws in this regard."
"Some countries have imposed severe penalties for the individuals who try to join the terrorist groups," he added.
Larijani is in Geneva to attend the 131st IPU (The Inter-Parliamentary Union) Assembly, which started on Sunday and will run until October 16.
Later on the day, the parliament speaker made a speech at the assembly about violence against women and gender inequality.
The Iranian delegation comprises seven MPs including one woman.
The IPU includes 145 parliament member states which convene assemblies twice a year (in the spring and autumn) every time in a different country. The organization is financed primarily by its members and has its headquarters in Geneva.
