Turkish President Recep Tayyip Erdoğan has said a military offensive Turkey launched against Kurdish militants in northern Syria and Iraq over the weekend should not remain limited to air strikes and that land forces should also be involved, local media outlets reported.Erdoğan, who spoke to reporters on his return from a trip to Qatar, said the Turkish General Staff and Defense Ministry would together decide on the involvement of ground forces.Turkish warplanes carried out air strikes on Kurdish militant bases in Syria and Iraq on Sunday, destroying 89 targets, the Defense Ministry said.Turkey considers the YPG to be an extension of the PKK, which is listed as a terrorist organization by Turkey and much of the international community.There were claims that Turkey is postponing the offensive due to objections from the US and Russia."
