While the Syrian Foreign Ministry sent an official letter to Beirut threatening to bomb Lebanese areas, the Land of Cedars will be without any senior officials in the coming week, as heads of its constitutional authorities travel outside the country. Meanwhile, sources have told Al-Monitor that the situation in the northern border area of Akkar has already begun to deteriorate significantly.

On March 14, the Lebanese Foreign Ministry received an official letter from its Syrian counterpart, the first of its kind since the Syrian civil war began. It appeared to be more than a message of blame and accusation, while less than a formal warning or Syrian threat against Lebanon.

The letter stated that "during the last 36 hours, large numbers of armed terrorist elements infiltrated from Lebanon into Syria.” It continued, "Syrian forces clashed with them within Syrian territory, and the clashes are ongoing.” The letter noted that "the Armed Arab Forces (the Syrian army) are still exercising self-restraint by not [targeting] the armed gangs inside Lebanese territories to prevent them from crossing into Syria, but this will not continue indefinitely."

The letter added that "Syria expects Lebanon not to allow those [elements] to use the border as a passageway because they are targeting the security of the Syrian people, violating Syrian sovereignty, and exploiting the good brotherly relations between the two countries." However, the message clearly mentioned that the Syrian army may be forced to resort to "bombing the gathering places of the armed gangs in Lebanon in the event of continued cross-border infiltrations."
