Ukraine is introducing two levels of air threat — yellow and red. Yellow will basically mean a drone raid, red a missile danger, including ballistic and massed attacks.

President Volodymyr Zelenskyy announced this after a report by Prime Minister Serhii Koretskyi.

The General Staff and the Air Force, together with the government, the Ministry of Defence, the Interior Ministry and the State Emergency Service, will set the indicators for each level on a weekly basis.

The warning sounds will change too: they will differ for the yellow and the red level. Clearer signals, differentiated by the level of threat, are being prepared.

One change is already in force: the siren is no longer sounded a second time to mark the all-clear. It now sounds only when an alert begins.

The President also ordered work on a finer geography of alerts, so that the warning and the response cover exactly the area where the threat is real.

The government and local authorities, together with the military, the Interior Ministry and the emergency service, are to set criteria allowing state bodies, local government and business to work during the yellow level.

The rules on where shelters are placed in cities and communities, including mobile ones, will be updated. Business is to get extra support to roll out modular shelters faster.

Kyiv will revise its public transport algorithms: during the yellow level the Syretsko-Pecherska metro line will run in full, and more surface transport will run between Lisova and Dnipro.

The curfew in the capital will be shortened. Other cities will be invited to review its limits in line with the real safety needs of people and the work of business.

The rules for schools and kindergartens stay unchanged. The Cabinet will provide extra financial support for medical facilities.

A weekly audit of response algorithms is also being introduced, with continuous consultations between the government, local authorities and business.

As a reminder, school buses in the Bucha community do not run while an alert is on.
