"A Pakistani official source told Al Arabiya: The US and Iranian delegations will arrive in Islamabad today at the same time"; "The second round of negotiations will be held as scheduled"

The arrival of US and Iranian delegations in Islamabad signals a continuation of critical negotiations, although the lack of information regarding a potential extension of the ceasefire raises concerns. This could imply a more fragile situation than anticipated, affecting regional stability and potentially influencing oil prices and market sentiment. Watch for any developments that might indicate shifts in diplomatic relations or military posturing.
