The Islamic State
group recaptured Albu Kamal
in eastern Syria
on Sunday, after a fierce fightback to save the last urban bastion of its collapsing "caliphate".
The jihadist rebound came as the United States
issued a surprise joint presidential statement saying there was "no military solution" to Syria's grinding six year war. However, the two countries have long backed opposite sides in Syria.
Kremlin today said US President Donald Trump
and Russian counterpart Vladimir Putin
made progress during a brief meeting on the sidelines of a summit in Vietnam.
Trump and Putin also "confirmed their determination to defeat ISIS", an alternative name for IS.
The jihadist group overran swathes of territory in Syria
in 2014, but its self-styled "caliphate" has since been whittled down to a pocket of land along the border between the two countries.
putting up a fierce defence there, particularly for the vital Syrian border town of Albu Kamal, said the Syrian Observatory for Human Rights monitoring group.
Syrian regime forces and allied militia from Lebanon, Iraq
and Iran overran Albu Kamal
on Thursday but lost the town again just two days later after a string of IS
counter-attacks and ambushes.
fully recaptured Albu Kamal, and regime forces and allied militia are now between one to two kilometres from the city limits," Rami Abdel Rahman, head of the Britain-based Observatory, said today.
Across the border, Iraqi forces seized today several villages from the jihadists in an offensive to capture the last IS-held section of their country.
The operation's commander, General Abdelamir Yarallah, said his forces captured Rumana
and 10 other villages as they worked their way towards the Euphrates Valley town of Rawa, the last Iraqi town still held by IS.
The jihadist group has in the space of a few weeks seen its "caliphate" shrink to a small rump and lost major cities such as Mosul
in Iraq, and Raqa and Deir Ezzor
Albu Kamal is
the last significant Syrian town it controls. Losing it would cap the group's reversion to an underground guerrilla organisation with no urban base.
rose to prominence in the chaos of Syria's conflict, which broke out in 2011 with protests against President Bashar al-Assad.
It has since evolved into a complex war that has killed more than 330,000 people, forced millions more to flee, and left much of the country in ruins.
Violence has broadly decreased since a series of "de-escalation zones" have been put in place in recent months in battlefronts across the country.
Today, Jordan announced that it had agreed with the United States
to formally establish such a zone in southern Syria
to build on a ceasefire already in place there.
Multiple rounds of peace talks hosted by the United Nations in Geneva have failed to resolve Syria's entrenched conflict.
