MNA � �Till yesterday, the US was afraid of the weapons of the revolutionary forces but today it is scared of their pen,� Expediency Council Secretary Mohsen Rezaei wrote on his Tweeter account.

Reacting to to Instagram blockings, the Iranian official added that �we will conquer the US with our pens.�

Following Washington�s controversial decision to designate IRGC as a �foreign terrorist organization�, Instagram has started to block pages of Iranian commanders. Facebook�s sister photo and video-sharing networking service has reportedly confirmed the measure, saying that it is acting on Washington�s sanctions law.

The targeted pages include those of the IRGC�s chief commander Major General Mohammad Ali Jafari, Major Quds Force commander Major General Ghasem Soleimani, Commander of the IRGC�s Ground Force Brigadier General Mohammad Pakpour, Chairman of the Chiefs of Staff of the Iranian Armed Forces Major General Mohammad Baqeri, Brigadier General Moussa Kamali, and Mohammad-Baqer Qalibaf, a former commander of the IRGC�s Air Force.

There are reports indicating that Facebook is also going to block accounts of IRGC personnel.

In a retaliatory measure, the Iranian Parliament approved a bill which recognizes American forces in West Asia, known as the United States Central Command (CENTCOM), as a terrorist organization.
