On 8 November, a suicide bombing on the Muhayya compound, which housed foreign workers in Riyadh, killed at least 17 people – mostly Arabs – and injured another 122. Saudi officials have blamed the Al-Qaeda network for the attack, which followed a sustained and public crackdown on militants in the kingdom. Security at expatriate housing complexes has also been improved after suicide bombers blew themselves up and killed 35 people at three housing compounds in the capital in May (MEED 10:11:03; 14:11:03).
