Second-in-command of the Islamic Revolution Guards Corps (IRGC), Brigadier General Hossein Salami on Thursday said that border security is a common and pressing need for neighbouring countries. He warned that if any neighbouring country fails to fulfill their obligation to protect their border than Iran will have no choice but to act on its own.We are, in principle, against intervening in the affairs of any country, but if they fail to abide by their obligations we will have [no choice but] to act,” said Salami, adding that “Terrorists, wherever they may be, even on the soil of neighbouring countries, we will find them, and if they do not give up acts of terrorism, we will deal with them without reservation.”In May this year, Iranian border guards trespassed three kilometres into Pakistani territory and shot dead a Pakistani citizen while injuring another in the Prom tehsil of Panjgur district in Balochistan.Iran, on many counts, has threatened to send forces into Pakistani territories.
