8.15pm GMT / 3.15pm EST: Some of the tear gas being used in Tahrir Square could have been manufactured as long ago as 1985, according to photos taken by Emad El-Din Shahin, a professor at the University of Notre Dame, Indiana.
The picture above shows Shahin holding several projectiles. In an email which was shared with the Guardian’s Jack Shenker, Shahin writes:
“As you will see from the canister I am holding, this gas bomb was manufactured in Feb. 1985!”
The image above shows the canister more clearly.
