Turkish President Recep Tayyip Erdogan has been under international criticism for preventing heavy weapons or forces to use his territory to help Kurds in Kobani. Allowing peshmerga fighters to cross into Syria appears to be the product of a compromise, a former Turkish diplomat says.

This made for an awkward situation for National Security Adviser Susan E. Rice, who announced such a cooperation ahead of an international strategy session. (associated press)
