Major U.S. stock-indexes little changed in late-morning trading on Tuesday as the ripples of the deadly explosions in Brussels were limited by a 1 percent rise in Apple (AAPL) and gains in healthcare stocks. At least 34 people were killed in twin attacks on Brussels airport and a rush-hour metro train in the Belgian capital, triggering security alerts across western Europe. European markets fell, while traditional safe havens gold and government bonds firmed up as reports of the events in the de facto capital of the European Union unfolded. Airline and travel-related stocks were the worst hit.

Most of Dow stocks in negative area (20 of 15). Top looser - American Express Company (AXP, -1,50%). Top gainer - Pfizer Inc. (PFE, +1,21%).

Most of S&P sectors also in negative area. Top looser - Conglomerates (-0,6%). Top gainer - Healthcare (+0,5%).
