Nearly three months after police cleared away the last of Hong Kong's pro-democracy street protests, lingering anger is stoking a new front of radical activism that has turned shopping malls and university campuses into a fresh battleground.
The U.S. Homeland Security Department said on Sunday it was not aware of any specific plot against U.S. shopping malls, backing away from comments by the department's chief that he takes seriously a threat by Somali-based Islamist militants against the Mall of America in Minnesota and other shopping sites in the West.
High-level nuclear negotiations between the United States and Iran resumed in Geneva on Monday as both sides work through technical and political differences to come up with an initial deal by a March 31 deadline.
Ukraine said on Sunday it feared unrest could spread beyond territory held by pro-Russian separatists, after an explosion killed two people at a memorial rally in an eastern city far from the front line.
