RIYADH: Saudi Arabia and Qatar on Friday "strongly" condemned a car bomb blast in Beirut that killed six people, including former finance minister Mohammad Chatah.
Saudi Arabia "has followed with great concern and disturbance the outrageous terrorist bombing" that rocked the Lebanese capital, said a statement on the official SPA news agency.
"The kingdom strongly condemns this cowardly criminal act and urges all parties in Lebanon to listen to the sound of rationalism and common sense... and insists on the need of the state to enhance its authority and that of the army across all Lebanese territories."
Chatah, an economist, former finance minister and Lebanon's ambassador to the United States, was the ninth high-profile anti-Syria figure killed in Lebanon since the 2005 assassination of former prime minister Rafiq Hariri.
Qatar's foreign ministry in a statement said it "strongly condemns such criminal acts that contradict all human values, and threaten to drag the region into chaos and instability".
The Gulf state "affirms its stance in rejecting all forms of violence regardless of the source or motivation," it added.
Lebanon's March 14 coalition, led by Rafiq's son Saad Hariri, has accused Syrian President Bashar al-Assad's regime of being behind the Friday blast. Damascus rejected the accusations.
Regional powerhouse Saudi Arabia backs Hariri's camp in Lebanon and has supported, along with Qatar, Syrian rebels against Assad's regime.
