Over a thousand killed, buildings destroyed and entire neighbourhoods reduced to rubble - the war in Israel between security forces and Hamas group operatives has had global implications.
Many countries, including the US, UK, France and Germany, have heightened security around "potential Jewish targets" and "pro-Palestinian protesters".
Here's how the war has impacted security around the world:
United States
Cities across the country, including New York, Los Angeles, Miami, and Houston, heightened security around synagogues in response to a Palestinian solidarity rally in Manhattan on Sunday. A thousand demonstrators gathered in solidarity with Palestinians, while a few hundred pro-Israel protesters counter-demonstrated.
New York Governor Kathy Hochul denounced the Palestinian solidarity rally as "despicable and morally reprehensible" and directed state landmarks, including the World Trade Center and Niagara Falls, to be illuminated in blue and white - the colours of the Isreli flag.
United Kingdom
The Scotland Yard has stepped up patrols across London in response to several incidents on social media related to the ongoing conflict in Israel.
The Metropolitan Police condemned the "glorification" of Hamas's terrorist activities and warned against hate crimes in a statement on Saturday night, following one of the biggest escalations of conflict in the Middle East in decades.
"We are aware of a number of incidents, including those that have been shared on social media, in relation to the ongoing conflict in Israel and the border with Gaza," the Met Police said in a statement.
"The Met has increased policing patrols across parts of London in order to provide a visible presence and reassurance to our communities. We remain in contact with partners and community leaders to listen to any concerns," it added.
France
In France, security at synagogues in the cities of Paris, Marseille, Lyon, and Strasbourg had been heightened since late September due to religious holidays.
French authorities ramped up security at Jewish temples and schools across the country, after a Jewish leader warned that the conflict could spill over the country.
France has the largest Jewish population in Europe and the third-largest in the world, with an estimated 500,000 people.French authorities announced that a pro-Palestinian rally scheduled for Monday evening in Lyon would be banned due to the potential for public disorder.
Germany
Germany increased police security at Jewish and Israeli institutions after Palestinian supporters celebrated the attack in the streets of Berlin. The Berlin police shared photos on social media of people celebrating Israel's attacks with sweet gestures.
German authorities have said they are closely monitoring "potential Hamas supporters" in Islamist circles.
"In Berlin, police protection has been immediately stepped up," Interior Minister Nancy Faeser told Bild newspaper. "The federal government and the regions are closely coordinating their actions."
Canada
Thousands of people in Montreal rallied in support of the Palestinian people on Saturday, holding "free Palestine" posters, waving Palestinian flags, and calling for boycotting Israel.
The Canadian police have stepped up security cover in sensitive areas, especially around synagogues.
"We are also reaching out to community partners to ensure they know we are here to support them," an Ottawa Police statement said. "Hate Crimes will not be tolerated and will be fully investigated."
Middle East
In Iran, large crowds gathered in major cities, such as Palestine Square in Tehran, waving Palestinian flags and cheering Hamas's offensive, which they called "Al-Aqsa Flood." Some billboards in the capital even proclaimed, "The great liberation operation has begun."
In Lebanon, Hezbollah, the Iranian-backed Shi'ite group, held a rally in Beirut to express support for Hamas. During the rally, participants chanted "Death to Israel." Hezbollah also claimed to have fired on Israeli positions in the contested Shebaa Farms border area.
In Iraq, pro-Palestinian protests erupted, with demonstrators burning Israeli flags and chanting anti-American slogans. The demonstrators stamped on and set fire to Israeli flags chanting "No to America, No to Israel".
