THE government must immediately halt tear gas sales to Greece after its “appalling” use on refugee protesters in Lesbos, campaigners demanded today.

Anti-arms campaigners are calling on ministers to review whether British-made tear gas was used by Greek riot police on refugees demonstrating for safe passage off the island on Saturday. 

Twelve thousand asylum-seekers have been sleeping on the streets for six days, with little food and water, after Europe’s largest refugee camp burnt to the ground last week.
