The government has planned to set up a heavily guarded Green Zone in the capital. According to sources, an Iraq-like Red Zone will be set up in Islamabad's red zone area over security situation, while Capital Development Authority (CDA) has already started work in this regard. Sources said diplomatic enclave, president house, PM offices, Pakistan secretariat and other important places will be guarded by the International Zone (Green Zone) in Islamabad. A concrete wall surrounding around G-5 and F-5 sectors from Khayban-e-Soharwardi to Margala road will be erected in the capital city.
