The convoy of buses and ambulances left the border region on Monday after a ceasefire took effect on Sunday.
"Their words ring hollow when they cut deals and allow terrorists to transit territory under their control".
After announcing the air strikes aimed at blocking the convoy on Wednesday, Col Dillon stressed that the coalition was "not bound by these agreements".
The airstrikes came amid US criticism of the deal, reflecting a growing outrage within the Trump administration over the decision to give the militants safe passage from the battlefield instead of killing them, and Iran-backed Hezbollah's leading role in it.
Samsung launches fitness smartwatches in health push
Users will be able to choose from an expanded selection of art, making the most of their TV even when it isn't in operation. Samsung gave it a round display and a slightly squared-off bezel, creating a rugged, Casio G-Shock kind of vibe.
Islamic State militants had for years held territory along the border, and captured 10 Lebanese soldiers in 2014 when they briefly overran the town of Arsal, one of the worst spillovers of the Syrian conflict into Lebanon.
Brett McGurk, the US Special Presidential Envoy to the global coalition to defeat ISIS, who just returned from a two-week jaunt across the Middle East including Iraq, the Kurdistan Region, and Syria, offered the US stance.
"Our coalition will help ensure that these terrorists can never enter Iraq or escape from what remains of their dwindling 'caliphate, '" McGurk added.
The militants had lost much of their mountainous enclave straddling the border since the two offensives began on opposite sides of the frontier.
But Lebanon's move to halt the fight after IS was squeezed into a small sliver on the border and then let the militants flee has further alarmed Washington. We, neither the Lebanese army, nor the Syrian army, agreed to a ceasefire.

He said it would allow hundreds of fighters to deploy along an "insecure" border, close to three Iraqi desert towns still under ISIL control.
"Our only consolation is that we knew the fate of the soldiers", the president said.
Earlier, Lebanon's President Michel Aoun hailed a "victory over terrorism". "If a soldier doesn't go into each room, clear it, and mark it as safe, then we can't say that we're done".
He explained that by "taking the time up front to surround these locations, instead of simply shoving them from one to another" coalition forces are able to "carry out the annihilation campaign so we don't simply transplant this problem from one location to another".
His army chief, Gen Joseph Aoun, meanwhile defended the evacuation deal, saying he had wanted to find the missing soldiers and not risk any more lives. The Syrian Observatory for Human Rights, based in London, reported on Wednesday that 64 combatants had been killed in the past 24 hours, and 150 in the past six days.
