In the Muslim world, the ones mourning Soleimani are the terrorists and their supporters.
Hizbullah leader Hassan Nasrallah called on more terror in response: "Meting out the appropriate punishment to these criminal assassins... will be the responsibility and task of all resistance fighters worldwide."
A Syrian spokesperson said, "Syria is certain that this cowardly US aggression... will only strengthen determination to follow in the path of the resistance's martyred leaders."
Islamic Jihad said that "America, with its crimes and siding with the Israeli occupation, is the enemy of the nation and the people."
Hamas offered its "sincere condolences to the Iranian leadership and the Iranian people for the martyrdom of Major General Qassem Soleimani - may God have mercy on him - one of the most prominent Iranian military leaders, who had a prominent role in supporting the Palestinian resistance in various fields."
The PFLP "sent its sincere condolences to the Iranian people and their leadership for the martyrdom of Major General Qassem Soleimani, who will not be forgotten by our Palestinian people, his prominent role in embodying the position of the Islamic Republic of Iran by supporting its rights and struggle against the Israeli occupation and supporting the resistance forces and developing their capabilities."
Meanwhile, Gulf News (UAE) celebrated Soleimani's death, reflecting reports of celebrations from Iraqis and others in the Gulf:
The killing of Qasem Soleimani, the head of Iran’s Revolutionary Guards, and considered to be the second most powerful man in Iran, after Supreme Leader Ayatollah Khamenei, marks a decisive victory against Iranian terror.
Arab states have long complained of Iranian interference in their internal affairs.
They also warned the international community that this was simply not a regional problem, but an international one.
