Suicide bombers hit three Saudi cities
Suicide bombers struck three cities across Saudi Arabia on July 4, killing at least four security officers in an apparently coordinated campaign of attacks as Saudis prepared to break their fast on the penultimate day of the holy month of Ramadan.
The explosions targeting US diplomats, Shi'ite worshippers and a security headquarters at a mosque in the holy city of Medina followed days of mass killings claimed by the Islamic State group in Turkey, Bangladesh and Iraq.
The attacks all seem to have been timed to coincide with the approach of Eid al-Fitr, the holiday that celebrates the end of the Islamic holy month.
A suicide bomber detonated a bomb at a parking lot outside the Prophet's Mosque in Medina, the second-holiest site in Islam, a Saudi security spokesman told state news agency SPA.
Five other officers were wounded.
