At least 21 civilians have been killed and 27 others injured since the US and Turkey announced a five-day break in fighting in northern Syria, according to the Kurdish Red Crescent.

"Since the ceasefire, we documented 21 civilians dead and 27 injured," a statement from the Kurdish Red Crescent released Tuesday said. "Not counted are all those who remains under the destroyed houses, got kidnapped or executed by the allies of Turkey."

The Kurdish Red Crescent, a humanitarian group, said the humanitarian situation has worsened as displacement camps are overcrowded and there is a shortage of shelters, food, medicine and water.

Since the Turkish military offensive began in Syria, about 200,000 people have been displaced to southern areas, according to the Kurdish Red Crescent.

"After the withdraw of hundreds of humanitarian organizations, the number of victims will increase very dramatically," the statement from the humanitarian organization read.

The Kurdish Red Crescent also accused the international community of not taking steps to "reduce this catastrophe."

The "ceasefire" agreement — referred to as a "pause" by Turkey — is scheduled to end today.
