Flags across New York are being flown at half-staff today to mark the anniversary of the Oct. 7 attack on Israel.

It's been two years since about 1,200 people were killed and roughly 250 others kidnapped. Forty-eight hostages remain in Gaza.

Landmarks, including the Empire State Building and Mario Cuomo Bridge, will be illuminated in yellow in solidarity with Israel and those still held captive.

State police are increasing patrols at religious sites following an attack outside a synagogue in Manchester, England that left two dead and three seriously injured on Yom Kippur.

Heightened uniformed patrols remain in place this week, and the state's counterterrorism intelligence unit and special operations teams are fully engaged.

Here is the list of landmarks to be lit:

1 World Trade Center
