MOSCOW (AP) -- Ukraine's prime minister has announced that cargo trucks registered in Russia will temporarily not be allowed to enter Ukraine, in response to Russia's ban on Ukrainian trucks.
Arseniy Yatsenyuk's announcement comes after Russia detained 152 Ukraine-registered trucks and banned Ukraine-registered cargo vehicles from entering.
Yatsenyuk said the ban on Russian trucks will be lifted when Russian authorities allow Ukrainian truckers into Russia again.
This tit-for-tat ban on truck transit began on Sunday when activists in Ukraine blocked Russian trucks along borders with Belarus and Western countries.
As relations between Moscow and Kiev have deteriorated over the annexation of Crimea and war in parts of eastern Ukraine, the two countries have imposed a series of sanctions on food imports on one another and halted direct air flights between the countries.
