Asterix artist pays tribute to Charlie Hebdo

"Asterix" artist Alberto Uderzo has come out of retirement to pay tribute to cartoonists slain earlier this week in a terrorist attack on the offices of the French satirical newpaper Charlie Hebdo.

Two Uderzo sketches referencing the incident were posted on the official Asterix Twitter feed.
