Tensions between Russia and Nato rise over Ukraine: Russian president Vladimir Putin has vowed a strong response should Nato deploy missile systems and troops in Ukraine, further raising tensions in the region, Reuters reports. This came in response to the US and Nato, which yesterday warned of “serious consequences” should Russia invade the ex-Soviet state. A buildup of Russian military forces on Ukraine’s border has fuelled speculation in Western capitals that Moscow is planning to invade the country.

Day one of the Iran nuclear talks went pretty well, with EU, Iranian and Russian diplomats all voicing optimism, Bloomberg reports.
