Rouhani made the remarks in the 28th International Conference on Islamic Unity in Tehran on Wednesday.
"In the past year, the Islamic world has seen much bloodshed, disagreement, and war. Unity will not be brought back to the Islamic world by repeating the world. The Islamic unity conference can be a first step in the tough path to unity.”
If we are going to unite, we must recognize Islamic sect as the branches of the same bough, he asserted.
Pointing out that the Islamic nation cannot accept parts of its lands to be ravaged by war and occupation, Rouhani said "If we seek unity in the Islamic world, we must consider the Sunni and Shia from Damascus to the Zeidi in Yemen and the Kurd in Iraq as the single Islamic nation.”
The president also called on the parties participating the event to condemn media, especially satellite channels, that work against one or another religious sect.
Last week Iran's security sources announced that they had shut down the headquarters of 27 satellite channels in the country which they said had been trying to spread disagreement among sects.
"The Islamic Republic will support the Muslims who fight for their land’s freedom in the face of occupiers,” he asserted.
