Updated at 6.14pm: The fatal terrorist strikes in the United States were condemned by Hong Kong's Chinese language newspapers on Wednesday.
The Oriental Daily News compared the terror attacks with Japan's surprise bombing of Pearl Harbour in 1941.
''These well-planned and careful attacks are like a war,'' the paper said in its editorial.
The Ming Pao Daily News wrote that the attacks had jeopardised US security and sounded a warning to the international community about how devastating terrorism could be.
''The US Government should think carefully about its foreign policy, especially in the Middle-East,'' the paper said.
The Sing Tao Daily predicted the attacks would lead to instability on global markets and disrupt US currency and oil prices.
