KYIV, Ukraine (AP) — Russian President Vladimir Putin signed the final papers to annex four regions of Ukraine while his military struggled to control the new territory. In a defiant move, the Kremlin held the door open for further land grabs in Ukraine. Speaking in a conference call with reporters, Kremlin spokesman Dmitry Peskov said that “certain territories will be reclaimed” and that Russia would continue “consulting” residents about joining Russia. He did not specify which additional Ukrainian territories Moscow is eyeing. The four annexed regions were added in violation of international laws. Ukrainian law enforcement officials, meanwhile, reported discovering more evidence of torture and killings in areas retaken from Russian forces.
