U.N. investigators have suspended visits to suspected chemical attack sites in Damascus suburbs for one day because of security concerns.
A U.N. statement said the team had planned to inspect one of the rebel-held suburbs on Tuesday after traveling to another affected district, Moadamiyeh, the day before. That visit was marred by sniper fire on a U.N. vehicle.
The United Nations said an assessment of the sniper fire determined that the team should wait until Wednesday before conducting another inspection, in order to "improve preparedness and safety."
