Speaking about her trip to visit Bosnia in 1996 Senator Clinton noted the following:

I remember landing under sniper fire. There was supposed to be some kind of a greeting ceremony at the airport, but instead we just ran with our heads down to get into the vehicles to get to our base. But it was a moment of great pride for me to visit our troops, not only in our main base as Tuzla, but also at two outposts where they were serving in so many capacities to deactivate and remove landmines, to hunt and seek out those who had not complied with the Dayton Accords and put down their arms, and to build relationships with the people that might lead to a peace for them and their children.

Then there is this video, which clearly shows Clinton not running from the landing site but instead having a very peaceful welcome in Tuzia:

Also from the Washington Post:

Numerous reporters, including The Washington Post’s John Pomfret, covered her trip. A review of nearly 100 news accounts of her visit shows that not a single newspaper or television station reported any security threat to the first lady. “As a former AP wire-service hack, I can safely say that it would have been in my lead had anything like that happened,” Pomfret said.
