The International Committee of the Red Cross’s new president, Peter Maurer, plans to meet in Damascus with Syrian President Bashar al-Assad and other senior officials on September 4 in an attempt to improve aid access to civilians.
The talks come as Syrian opposition activists say a Syrian government warplane on September 3 bombed a building in a rebel-held town, killing more than 20 people.
The Syrian Observatory for Human Rights said several women and children were among those killed by the raid in the northern town of Al-Bab.
In a Damascus suburb, a car bombing badly damaged a building, reportedly killing five people.
Syrian state media said women and children were also among the victims there.
SANA news agency blamed the bombing on a "terrorist group."
