Wonder what's up! Some USA embassies worldwide to close on Sunday August 4

Only in the Muslim world, Sunday is a working day.  Muslim countries have Fridays as their official weekly holiday.  Embassies in non-Muslim countries  would be closed on Sundays anyway .... so the logical conclusion is that the mighty USA  has info on harm being planned for them in the countries they consider to be their allies.

From NYTimes:
....The United States said it would close an unspecified number of embassies around the world on Sunday over security concerns.
State Department spokeswoman Marie Harf on Thursday called the step “precautionary” but declined to specify the threat or list which missions would be closed.
“The Department of State has instructed certain US embassies and consulates to remain closed or to suspend operations on Sunday, August 4,” Harf told reporters.
The decision was taken “out of an abundance of caution and care for our employees and others who may be visiting our installations,” she said.
Harf said that the embassies would be closed specifically on Sunday, with an assessment afterwards on whether to reopen them.
“It is possible we may have additional days of closing as well,” she said..........
