Google has begun a search for one of its executives who has gone missing Egypt.
Head of marketing for Middle East and North Africa, Wael Ghonim has not be heard from for a week, with his wife and family claiming no knowledge of his whereabouts following his attendance at a conference last week in Cairo.
The last known communication with Ghonim is understood to be a series of messages he posted on Twitter, which said:
"Despite all the warnings I got from my relative and friends, I'll be there on #Jan25 protests. Anyone going to be in Gam'et Dewal protest?"
"Egypt after #Jan25 is no way going to be the same as Egypt before it. Today we proved so many points."
"Heading to Tahrir square now. Sleeping on the streets of Cairo, trying to feel the pain of millions of my fellow Egyptians. #Jan25"
The final message to be sent on 27 January, read: "Pray for Egypt. Very worried as it seems that government is planning a war crime tomorrow against people. We are all ready to die."
Egypt has been in chaos for a week as thousands have gathered to protest for the resignation of President Hosni Mubarak after 30 years of rule. This led to violent clashes between protestors and supports of Murbarak yesterday.
