TOPSHOTS Algerians walk past a wall on which a graffiti reads in Arabic "no to hydraulic fracturing " on March 5, 2015 during a protest at Somoud Square in the Sahara desert village of In-Salah, south Algeria, against the exploration of shale gas. Anti-shale gas demonstrations have increased in the cities of the Algerian Sahara since late December, when Algerian oil company Sonatrach announced it had successfully completed its first pilot drilling in the In-Salah region. Sonatrach announced in early February that its exploratory drilling for shale gas using hydraulic fracturing would continue despite mounting hostility among people living nearby.
