Qatar's Prime Minister Sheikh Hamad bin Jassem Al-Thani has said his country, which hosts the US Central Command, would oppose any military attack against Iran.
"The Iranians and the Americans know that Qatar rejects any military action against Iran," he said in an interview with the Doha-based Al-Jazeera, excerpts of which were broadcast Wednesday.
Sheikh Hamad, who also holds the foreign affairs portfolio, said the energy-rich nation will not allow the use of its territory for attacks on the Islamic republic.
"We will not accept, and this is very clear, any act of aggression against Iran (being launched) from Qatar," he said.
