German Chancellor Angela Merkel has appeared unsteady and shaky for the second time in 10 days.

The brief incident Thursday morning happened at a government ceremony in Berlin as Merkel stood alongside Germany’s president.

64 year old Merkel was handed a glass of water but rejected it, and appeared fine when she arrived in parliament half an hour later.

On Tuesday last week, Merkel’s whole body shook as she stood outside in hot weather alongside Ukraine’s president. Merkel said afterward that she was fine after drinking three glasses of water, which she “apparently needed.”

Hot weather in Germany has continued this week though temperatures in Berlin dropped overnight.
