Defence ministers from 40 Muslim-majority countries have gathered in Saudi Arabia to launch a military coalition aimed at fighting terrorism both in its "ideology and in its violence".
Prime Minister Shahid Khaqan Abbasi and Chief of Army Staff General Qamar Javed Bajwa will be traveling to Saudi Arabia next week for a crucial conference on the Islamic Military Counter Terrorism Coalition (IMCTC).
Salman said the issue of terrorism would come to an end as more than 40 Islamic countries are sending a very strong signal that they would work together to support each others' efforts, whether in military, financial, intelligence and political aspects.
Sunday's meeting is expected to discuss means of fighting terrorism and drying up its finances.
The alliance was formed in 2015 under the leadership of Prince Mohammed, whose heir to the throne in June had shaken the political scene across the region. -Islamic summit in Riyadh in May unveiled that the alliance member states were ready to deploy 34,000 troops with a view to supporting operations against terrorist groups in Iraq and Syria.
Saudi Arabia accuses Iran of supporting armed groups across the Middle East, including Lebanon's Shiite Hezbollah and Yemen's Huthi rebels.
The meeting will be attended by Dr. Mohammed Al-Issa, head of the Muslim World League (MWL), Abdulilah bin Osman al-Saleh, General Secretary of Islamic coalition, and Raheel Sharif, military commander of IMCTC's.
General (Retd) Raheel Sharif said while all individual states are making efforts against the menace of terrorism, the required level of the synergy and the resources are lacking.
Qatar's flag was also absent.
Egypt, which sent a military official and not its defense minister to Sunday's meeting, is reeling from a Friday attack on a mosque that killed more than 300 people during prayer time.
Prince Mohammed said Friday's "painful event" was a reminder of the "danger of terrorism and extremism".
A corruption purge saw around 200 members of the Saudi elite including princes, ministers and business tycoons arrested or sacked earlier this month.
