The US embassy in Cairo has condemned Sunday's mob killing of four Shia Muslims in a Giza village, which has stoked fears of worsening sectarian frictions in Egypt.
"We call on the Egyptian government to follow through on its pledge to ensure that the perpetrators of this heinous crime are held accountable under the law, and we urge a thorough and transparent investigation," read an embassy statement released Monday.
Four Egyptian Shia-Muslims were killed in a mob attack in the village of Zawyat Abu Musalam in Egypt's Giza governorate on Sunday, after hostile crowds converged outside a house in which a group of Shia Muslims were holding a meeting.
The violence, which included the murder of four Shia residents and the injuring of several others, was captured on video.
Egypt's presidency and cabinet have both condemned the incident and vowed to prosecute those responsible.
