LUHANSK, Ukraine, Dhu-AlQa'dah 18, 1435, Sep 13, 2014, SPA -- A convoy of more than 200 white trucks crossed the Russian border to deliver humanitarian aid to a battered Ukrainian city on Saturday, a move made without Kiev's consent yet met with silence by Ukraine's top leaders, AP reported. "Early in the morning, we entered Ukraine to bring aid to Luhansk," said Yury Stepanov, a Russian who was overseeing the convoy. "We came in around 215 vehicles," he added, as workers unloaded boxes into a local warehouse. The much-needed aid arrived as fighting flared again between pro-Russian rebels and government forces, further imperiling an already fragile cease-fire in the region. On Saturday, Ukraine's military operation in the east said it had repelled a rebel attack on the government-held airport of Donetsk, which came under artillery fire from rebel positions late on Friday. Ukrainian authorities also admitted for the first time since the cease-fire started last week that they have inflicted casualties on the rebel side. -- SPA 23:10 LOCAL TIME 20:10 GMT www.spa.gov.sa/w
