Ayman al-Zawahiri,Al-Qaeda's second in command, vowed the terror group will not stop attacks on USA as long as the United States strikes Muslims on their land.
He declared attacks will continue in a videotape aired Wednesday.
"If we are hit in our countries, we will not stop striking you in your country," Zawahiri said in the video broadcast on pan-Arab television station Al-Jazeera.
"It seems you will undertake a painful journey of failed negotiations before being forced to go back, God willing, to negotiation with the real forces," said Zawahiri.
"As our emir Sheikh Osama bin Laden, God keep him, said, 'Like you bomb, you will be bombed, and like you kill, you will be killed'," he added.
