Now the AfD has the third largest number of MPs in the Bundestag. And the party's leaders say the government should get ready for tough times. The question is, will Merkel bend to the pressure?

Turkey plans to deploy troops to the Syrian province of Idlib as a deal agreed to by Russia and Iran to create de-escalation zones. The Turkish military is to patrol inside the city, which is controlled by the rebel group Hayat Tahrir al Sham, which has links to Al Qaeda.
