High-level security meeting between Jordan, Syria, Iraq, and Turkey tomorrow.

Reuters reported today, Saturday, citing a Turkish diplomatic source, that "high-level delegations from Turkey, Jordan, Syria, and Iraq will meet in Amman tomorrow, Sunday, to discuss security cooperation and regional developments."
According to Al Arabiya, last month, Turkish Foreign Minister Mevlut Cavusoglu said, "The four countries will take steps towards combating ISIS collectively in the region, aiming to hold the first meeting on this issue in Jordan."
The Turkish diplomatic source, who requested anonymity, stated that "foreign ministers, as well as defense ministers or military leaders and heads of intelligence agencies from the four countries, will attend the meeting."
The source added that "officials will discuss cooperation in security, counterterrorism, organized crime, as well as regional developments."
Since the overthrow of Bashar al-Assad in December, Western and regional countries have warned of the possibility of ISIS resurgence.
