ISIS conducted an unprecedented series of complex suicide attacks in regime-held Tartus City and Jableh on the Syrian Coast on 23 MAY, killing at least 150 civilians and wounding over 200 others. ISIS will likely escalate its attacks against Alawites on the Syrian Coast during the upcoming holy month of Ramadan. Meanwhile, ISIS seized at least six villages in Northern Aleppo Province in a major setback for efforts by the U.S. and Turkey to deny ISIS access to the Syrian-Turkish Border.
Russia is waging a multi-front campaign against Turkey in order to weaken NATO in line with its strategic objectives. The use of a high-end Soviet-era MANPADS against a Turkish helicopter in southeastern Turkey on May 13 could indicate that Russia is providing meaningful military support to the Kurdistan Workers' Party (PKK) insurgency. The incident, if indeed an escalation by Russia, is yet another infringement of a sovereign NATO partner.
The International Syria Support Group (ISSG) agreed to new measures to reinforce a nationwide 'cessation of hostilities' following a meeting on May 17. The ISSG pledged support to a campaign of "air bridges" starting on June 1 if actors continue to deny humanitarian access to besieged regions. The ISSG also threatened to exclude parties with a "persistent pattern of noncompliance" from the ceasefire. The meeting nonetheless failed to set a clear date for the resumption of the Geneva III Talks.
A temporary ceasefire ended in Aleppo City on May 11, sparking a new wave of violence throughout the city and its outskirts. The U.S. and Russia brokered the local truce on May 5 as part of an effort to reinstate a nationwide 'cessation of hostilities'. Meanwhile, Lebanese Hezbollah military chief Mustafa Badreddine reportedly died in an unidentified explosion near Damascus less than a week after the Islamic Revolutionary Guard Corps suffered one of its largest single-day combat losses in Syria.
The U.S. and Russia brokered an agreement to extend a temporary "regime of silence" to Aleppo City for 48 hours beginning on May 5. The agreement follows 10 days of violence in Aleppo City that killed at least 250 people and damaged at least 5 hospitals. Nonetheless, the renewed diplomatic effort to prevent an escalation in Aleppo City and re-institute a nationwide 'cessation of hostilities' faces severe challenges.
U.S. President Barack Obama announced his decision to deploy 250 additional Special Operations Forces to northern Syria, raising the total number of U.S. personnel in the country to 300. Obama emphasized that the new forces will “not be leading the fight on the ground” but instead work to recruit, train, and assist Sunni Arab fighters within the U.S.-backed Syrian Democratic Forces in preparation for future operations to isolate the ISIS stronghold of Ar-Raqqa City.
Russia actions raised concerns after reportedly redeploying artillery units and personnel to the vicinity of Aleppo City, according to senior U.S. officials. The deployments come amidst a major breakdown in the Geneva III Talks. Meanwhile, the Syrian Kurdish YPG and its affiliated Asayish internal security forces engaged in heavy clashes with pro-regime forces in Qamishli in Hasaka Province following an altercation at a pro-regime checkpoint.
