DUBAI (AFP) - Osama bin Laden has reiterated a call for aid to flood victims in Pakistan, in the second such audio message posted online in as many days, a US monitoring group said on Saturday. In a speech entitled 'Help Your Pakistani Brothers, the Al-Qaeda leader focuses on the reluctance of Arab and Muslim countries to help Pakistanis, singling out Gulf states, Malaysia and Turkey, SITE Intelligence Group said. The response did not match the level of the disaster, said the voice whose authenticity could not be immediately verified. Osama said Arab and Muslim leaders had not paid any visits to flood-hit areas unlike UN chief Ban Ki-moon, and added Arabian Peninsula oil wealth should be used as it 'belongs to all Muslims. The 13-minute recording appeared on the Internet around 24 hours after bin Laden expressed concern about global climate change and flooding in Pakistan in a similar audio message aired on the Internet. The number of victims caused by climate change is very big... bigger than the victims of wars, bin Laden said in Fridays tape, which would have been the first time he had spoken publicly since March 25.
