Iran is ready to help the US stabilise Iraq if Washington presents a timetable for a withdrawal of its troops, Tehran’s top security official said on Sunday.

In an interview with the Financial Times, Ali Larijani, head of the Supreme National Security Council, which answers to Ali Khamenei, the supreme leader, rejected Washington’s accusations that Tehran is providing weapons to Iraqi militias, insisting the trouble with Iraq was that the US administration was pursuing a “dead-end strategy”.
