A large wildfire that broke out near Assiros, outside the northern Greek city of Thessaloniki, remains active and uncontained, with multiple fronts still burning. The fire, which began on Tuesday afternoon, has triggered an extensive firefighting effort involving over 150 firefighters, 75 vehicles, and seven ground teams, supported by aerial units and emergency resources from local municipalities.

As of Wednesday morning, firefighting efforts intensified with the arrival of aircraft and helicopters, while Bulgarian firefighters joined the operation after crossing the nearby border, highlighting regional cooperation in response to the growing threat.

Authorities issued a 112 emergency alert late Tuesday night, urging residents in the nearby areas to remain on standby for potential evacuation as the situation developed.

Traffic has been disrupted along the old Thessaloniki–Serres national road. Local government crews have deployed water trucks and heavy machinery to assist with containment.

In Grevena, another fire that began in the remote mountainous area of Skala Deskatis showed signs of improvement late Tuesday, though it briefly reignited due to strong winds. Fire crews managed to confine it to smaller pockets by midnight, though monitoring continues due to the risk of further flare-ups. The blaze affected both pine and fir forests at higher elevations and shrubland in lower areas.

Fires in other parts of Greece, including Larisa, Chania, and Koropi, have largely been brought under control.
