Interpol has issued an arrest warrant for Osama bin Laden's right-hand man at the request of Egyptian police authorities, the organisation said in a statement.
It said Aiman Al Zawahri, born in Giza, Egypt in 1951, is the leader of the Al Jihad group and was emerging as one of the key figures in bin Laden's al-Qaeda network.
"Interpol's 179 members are hereby formally requested to try to trace him and if successful, notify the Cairo Interpol bureau as well as Interpol's headquarters in Lyon, France," the statement said.
It was released ahead of a news conference during Interpol's 70th General Assembly in Budapest.
