German foreign minister said on Saturday that an 'air bridge' may be necessary to deliver aid to the besieged Syrian city of Aleppo, which is currently facing a humanitarian crisis due to the ongoing Syrian crisis.

Foreign Minister Frank-Walter Steinmeier told the Welt am Sonntag newspaper on Saturday that Germany was in talks with the U.S., Russia and the United Nations to try and organize "urgent humanitarian assistance" to the northern Syrian city.

Despite calls for a cease-fire and Russia's promise of a three-hour daily respite from airstrikes to allow in humanitarian aid, there has been no letup in the violence.

Steinmeier said "if both parts of Aleppo continue not to receive sufficient humanitarian supplies, we should also consider the possibility of assistance by air, especially medical goods."

Steinmeier also criticized the Assad regime for using chlorine gas against the people of Syria and condemned the use of unlawful chemical weapons.

Furthermore, he demanded that all sides make the effort to protect civilians, including innocent men, women and children, who are targeted by chemical weapons.
