WASHINGTON (AP) — President Barack Obama has ordered a review of U.S. deportation practices to see whether immigration enforcement can be more humane, the White House said Thursday.

By Phil Stewart WASHINGTON (Reuters) - The United States is weighing requests for military assistance from Ukraine, including both lethal and non-lethal support, two U.S. officials said on Thursday, as a prominent U.S. senator urged approval of any arms sought by Kiev. The U.S. officials, who asked to speak on condition of anonymity because of the sensitivity of the diplomatic discussions, said the United States had already decided to move ahead with some aid, including military food rations. The U.S. government was still weighing other requests, including for lethal aid, which were made through the U.S. State Department, the officials added, without offering more details. Earlier on Thursday, the Wall Street Journal reported that Ukraine's interim government asked for arms, ammunition and intelligence support but the United States had decided against further assistance beyond rations because of concerns about stoking tensions with Russia.
