Arab leaders are condemning Thursday's terrorist bombings in Madrid.
Leaders throughout the region are sending messages of condolence to Spain's King Juan Carlos.
Egyptian President Hosni Mubarak, Arab League Secretary-General Amr Moussa, Libyan leader Moammar Gahdafi, Syrian President Bashar al-Assad, Jordan's King Abdullah and Lebanese Prime Minister Rafiq Hariri all strongly denounced the bombings, and expressed shock and sadness.
Mr. Hariri called for drastic measures to end such acts of terror. President Mubarak condemned all forms of violence and terrorism in a telephone call to the Spanish king. President al-Assad expressed profound pain at what he described as criminal and terrorist acts.
Newspapers throughout the Arab world ran banner headlines describing the terrorist attack. Some called the tragedy Spain's September 11, referring to the 2001 attacks on the United States.
None of the terrorist experts in the Arab world contacted by VOA was willing to speculate on who might have carried out the attacks, saying there are still too few details to make an assumption about the identity of the perpetrators.
On Friday, Spanish officials said all lines of investigation remain open.
