(Wall Street Journal) Russia withheld a crucial piece of information from the U.S. before the Boston bombings, U.S. officials say, bolstering a concern that distrust between the two governments erased an opportunity to avert the disaster.

The texts suggested Tsarnaev was interested in joining militant groups that Russia blames for attacks in the Caucasus region, according to U.S. officials briefed on the investigations.
