ISTANBUL (Reuters) - Turkey and Iraq have agreed to open a second border gate and its construction will begin once the necessary security measures are taken, Turkey s customs minister said on Thursday.  I had the impression that the Iraqi government agrees that there should be a second border gate , Bulent Tufenkci told Anadolu news agency. He said the planned gate would be near the northern Iraqi city of Mosul, in a region where Islamic State and Kurdish PKK militants still pose a security threat.  Once steps are taken to secure the path, there is no other obstacle for us,  he said.
