Just back from a whirlwind 10-day trip to Asia, the Middle East and Europe, Secretary of State John Kerry is heading across the Atlantic again for nuclear talks with Iran as a November 24 deadline for a deal looms.

The State Department says Kerry is leaving for Europe on Monday, starting his trip in London where he will hold talks with European and Mideast officials on the Iran negotiations as well as volatile situations in the Mideast.

From London, Kerry will travel to Vienna, where the next round of nuclear talks is set to begin on Tuesday and continue through the week, the department says.

Kerry may not take part in all the negotiating sessions in Vienna and other stops are possible, officials said Monday.
