Regional anger over Houthi attacks on Saudi Arabia has spilled into a wave of formal condemnations. The strikes hit King Fahd International Airport in Dammam and the Shaybah oil field in the country's eastern region. Four people were killed and ten others wounded in the assaults, according to the NNI news agency. Governments across the Middle East have spoken out, with the United Arab Emirates, Qatar, Bahrain and Jordan among them. The Muslim World League has also weighed in against the attacks. The choice of targets drew particular criticism, since an airport serves civilians and Shaybah sits at the heart of Saudi oil infrastructure. Houthi assaults on the kingdom have continued despite repeated international calls for restraint. The statements issued so far amount to political condemnation, with no sign yet of a joint response.
