The Syrian government collapsed after a surprise rebel offensive.
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.

The Iranian Foreign Ministry released a statement Sunday saying it continues to monitor the situation in Syria and that "the future of Syria will only be decided by the people."

"It is expected that the relations between Iranian and Syrian nations continue with a long-term and wise approach, based on common interests and benefits," the statement read, in part.

Israeli Prime Minister Benjamin Netanyahu weighed in Sunday on the fall of the Assad regime in Syria, calling it a "historic day" in the Middle East.
Netanyahu said that due to Syrian troops abandoning their positions in the buffer zone between Israel and Syria, the Israel Defense Forces has seized those positions.

"We will not allow any hostile force to establish itself on our border," Netanyahu said.
Netanyahu and Defense Minister Israel Katz on Sunday visited Mount Bental in the Golan Heights, an observation point toward the Syrian border.
"This is a historic day in the history of the Middle East," Netanyahu said. "The Assad regime is a central link in Iran's axis of evil -- this regime has fallen."
Netanyahu claimed the fall of Syrian President Bashar al-Assad was a "direct result" of the blows Israel has inflicted on the main supporters of his regime, Iran and Hezbollah.
"This has created a chain reaction throughout the Middle East of all those who want to be free from this oppressive and tyrannical regime," Netanyahu said.
