Police in Europe remain on high alert after the foiled Belgian terror plot and the atrocities in Paris.
A weekly anti-Islam rally in Dresden, Germany, has been cancelled by police due to a threat of an attack on one its leaders.
It comes after German security authorities said on Friday that they had specific warnings of a risk of militant attacks on central railway stations in Berlin and Dresden.
Nearly 300 troops have being deployed to guard potential targets of terrorism in Belgium, the defence minister said on Saturday.
Steven Vandeput told reporters they are being stationed at locations such as the US and Israeli embassies in Brussels and NATO and EU institutions after anti-terror raids captured a number of suspected Islamic extremists last Thursday.
Troops will reinforce police until this coming Thursday, when authorities will review the national threat level.
The country's terror warning system has been raised to level three, the second highest, following the raids.
"It's very important to say that this wasn't a simple decision. But it was necessary, at a time when police are overly engaged, for the army to enter in a supporting role," Mr Vandeput said.
The Democratic presidential candidate may also have shown his cards on his choice of running mate.
