Tensions between Russia and Ukraine have escalated one day after Moscow claimed it thwarted an incursion into Russia-held Crimea by Ukrainian saboteurs, with Kyiv putting troops near the peninsula on highest alert and Russia announcing increased security measures and new naval exercises in the Black Sea. Meanwhile, the U.S. ambassador to Ukraine said Washington has seen no evidence supporting the claim by Russia', which accused Kyiv of plotting "terror" in Crimea and reporting that two members of its security forces were killed in clashes last weekend with the alleged assailants.
