the real reason of the clashes:
Iran’s Islamic Revolution Guards Corps (IRGC) Ground Force has managed to fight off a team of militants affiliated with the Pakistan-based so-called Jaish al-Adl terrorist group in the country’s southeastern province of Sistan and Baluchestan close to the border with Pakistan.
The IRGC Ground Force’s Quds Base said in a statement on Wednesday that the IRGC servicemen, having fully detected the fully-armed terrorists and been informed of their plans for terrorist activities, clashed with them in Kastag village of Rask County.
The statement added that a terrorist was killed in the operation, while the rest fled the area into southwestern Pakistan.
