Syria's Assad is now in Moscow, Russian state media says
Rebel forces in Syria captured the capital Damascus and toppled the regime of President Bashar al-Assad in a lightning-quick advance across the country.
As Assad resigned and fled Syria, rebel forces moved into Damascus as citizens celebrated there and in the streets of Aleppo, where the rebel offensive began 11 days ago.
Meanwhile, the ceasefire in Lebanon is holding despite ongoing Israeli airstrikes on Hezbollah targets, which Israeli officials say are responses to ceasefire violations by the Iranian-backed militant group.
The Israel Defense Forces continued its intense airstrike and ground campaigns in Gaza, particularly in the north of the devastated Palestinian territory.
Tensions also remain high between Israel and Iran after tit-for-tat long-range strikes in recent months and threats of further military action from both sides.

Israel bombed Syrian chemical weapons sites, foreign minister says
Israeli Foreign Minister Gideon Saar told reporters on Monday that Israeli forces "attacked strategic weapons arrays, residual chemical weapons capabilities, missiles and long-range rockets" inside Syria to prevent them from falling into the hands of "extremist elements."
Israeli forces have been striking inside Syria and occupying positions on Syrian territory in recent days, as rebel forces -- some with roots in jihadist organizations -- surged into major Syrian cities and precipitated the collapse of President Bashar Assad's regime in Damascus.
The Israel Defense Forces announced on Sunday it had taken up positions in the demilitarized buffer zone between Israel and Syria established by a bilateral 1974 agreement.
Saar said the presence of "armed men" in the zone and their alleged attacks on United Nations positions there prompted the Israeli decision to cross the border.
Saar said Israeli deployments into the buffer zone are "targeted and temporary" and intended to prevent an "Oct. 7 scenario from Syria," referring to last year's devastating Hamas infiltration attack into southern Israel.

Israeli forces cross into buffer zone separating occupied Golan Heights from Syria
Israel Defense Forces tanks and armored vehicles have entered the buffer zone that separates the Israeli-occupied Golan Heights from Syria on Sunday night.
The move puts IDF troops in operations on four fronts in the Middle East, Israeli military chief of staff Herzi Halevi said on Sunday, according to the Associated Press.
The advancement into Syria comes after the fall of President Bashar al-Assad's regime to Islamist rebels.
Israeli Prime Minister Benjamin Netanyahu said the decision was made to "protect Israeli residents after Syrian troops abandoned positions," according to AP.
The IDF has reportedly warned Syrian residents in five southern communities to stay home for their safety.
Israeli forces on Sunday also took over the Syrian side of Mount Hermon in the Golan Heights, according to AP.

Iranian foreign minister says he fears 'renewed civil war' in Syria
Iranian Foreign Minister Abbas Araghchi commented on the fall of Syria's government during an interview on Iranian state TV on Sunday.
He said Syria's ousted president, Bashar al-Assad, was “surprised” and “complained about the way his own army was performing.”
Araghchi also said Iran was fully aware of the situation in Syria through “the intelligence and security system of our country.”
Iran is monitoring the developments in Syria and is concerned about the “possibility of a renewed civil war or a sectarian war between different sects or the division of Syria and the collapse of Syria and its transformation into a haven for terrorists,” Araghchi said.

US strikes 75 ISIS targets in Syria
The United States launched dozens of against ISIS targets in central Syria on Sunday in an attempt to "disrupt, degrade and defeat" the terrorist group, according to the head of the U.S. Central Command.
CENTCOM Commander Gen. Michael Erik Kurilla said in a statement that 75 ISIS targets were hit in precision airstrikes Sunday in Syria. He said the mission was carried out by U.S. Air Force assets, including B-52s, F-15s and A-10s.
"There should be no doubt -- we will not allow ISIS to reconstitute and take advantage of the current situation in Syria. All organizations in Syria should know that we will hold them accountable if they partner with or support ISIS in any way," Kurilla said.
Kurilla said the strikes hit known ISIS camps and operatives in central Syria.
During a speech at the White House on Sunday, President Joe Biden mentioned the U.S. strikes on ISIS targets in Syria. He said U.S. forces are also bolstering security at detention facilities in Syria where ISIS fighters are being held.
"We're clear-eyed about the fact that ISIS will try to take advantage of any vacuum to reestablish its capability and to create a safe haven," Biden said. "We will not let that happen."

During a visit on Sunday to a Syria observation post in the Golan Heights, Israeli Prime Minister Benjamin Netanyahu said the IDF seized the buffer zone due to Syrian troops abandoning their positions there. "We will not allow any hostile force to establish itself on our border," Netanyahu said.
