Reuters has released a U.S. Embassies-sourced image indicating which embassies will be closed this Sunday due to terrorist threats abroad. Although the map appears to be detailed, outlining both embassy and consulate closure, it seems to omit a couple details. First, it has been confirmed that the embassy in Israel is also closing on Sunday. Second, the State Department also mentioned embassies in South Asia, which presumably would include Pakistan. Neither of these is indicated on the graphic.
The US State Department announced a travel warning for US citizens abroad, citing the same terrorist threat.
