Turkey has submitted a proposed joint defense pact with Saudi Arabia and Pakistan to Parliament for ratification. The move places the security agreement before Turkish lawmakers for formal approval. Parliament's Foreign Affairs Committee could discuss the proposal as early as Thursday. Three parliamentary sources said the committee was expected to take up the measure then. Lawmakers will assess whether the government should approve Turkey's participation in the joint defense arrangement. The report did not spell out the pact's operational provisions or how long its commitments would last. No full-parliament vote date had been announced.
