NUSA DUA, Indonesia, and KYIV, Ukraine — President Biden said it was "unlikely" that a missile that caused an explosion in eastern Poland was fired from Russia, but he said the information was "preliminary" and said Poland's allies would support a full investigation.
The explosion came as Russia unleashed a wave of missile strikes Tuesday at cities across Ukraine, hitting residential buildings and knocking out electricity in urban areas. In neighboring Poland, two people were killed in an explosion at a grain processing facility, just a few miles from its border with western Ukraine.
