Who was Qasim Sulaimani?
The death of one of the most important people has long been a major blow to Iran in conflict with the United States, which has increased steadily after militants attacked the US embassy in response to a US airstrike on Iranian-backed Iraqi militia last week.
It may be recalled that Qasim Sulaimani, who was instrumental in the ongoing war in Iraq and Syria, led the revolutionary branch abroad and was considered a celebrity both at home and abroad.
Also, he was particularly active in the promotion of Iranian influence in the Middle East, which the US and Iranian regional rivals Saudi Arabia and Israel are keen to keep an eye on.
Qasim Sulaimani has been successful in avoiding attacks by Western, Israeli and Arab agencies over the past two decades.
His Qadis force had the responsibility of conducting operations outside the Iranian border, which supported President Bashar al-Assad in the civil war in Syria since 2011 when he was nearing failure and even defeating ISIS in Iraq.
Qasim Sulaimani became the head of the Al-Quds Force in 1998 and has worked in that position for many years, during which Iran's relations with Lebanon Hezbollah, Syrian President Bashar al-Assad's government and Iraqi militias strengthened.
