Our news desk has wrapped together everything we know about the convoy:
A Russian aid convoy has resumed its travel toward Ukraine, with at least part of the convoy heading south toward the rebel-held Luhansk region.
Russian officials have not said where the convoy of nearly 300 trucks is headed. Russia initially said the convoy would cross into the government-controlled Kharkiv region.
Reports on August 14 said the convoy was now in Russia's southern Rostov region, neighboring Luhansk.
Moscow has dismissed claims the convoy is a pretext to send military aid to the separatists fighting government forces in eastern Ukraine.
Meanwhile, Ukraine said it was sending its own aid convoys to the east, with dozens of trucks leaving Kyiv, Dnipropetrovsk, and Kharkiv for a government-held town near Luhansk on August 14.
Local officials said Luhansk came under shelling on August 14, causing civilian casualties.
Lots of these going about. Here's a Transformers one.
With Strelkov's fate uncertain, things just got even more complicated for the separatists:
The leader of pro-Russian rebels in eastern Ukraine's Luhansk region says he is stepping down, the second senior separatist figure to resign in a week.
Valery Bolotov said on August 14 that he was suspending his work as leader of the self-proclaimed Luhansk People's Republic, citing a wound that he said was hampering his efforts in the job.
He said the rebel "defense minister," Ihor Plotnitsky, would be asked to take his place.
Bolotov's announcement came seven days after Aleksander Borodai, the leader of separatists in the neighboring Donetsk region, said he was resigning his post as prime minister of the self-proclaimed Donetsk People's Republic.
It also followed conflicting statements by separatists on August 13 about the status of the military chief of the Donetsk separatists, Igor Strelkov, who some reports said had been wounded.
An update from our news desk on Putin's visit to Crimea:

Good point.
The convoy has still not arrived, whether it is even supposed to arrive. Meanwhile, Putin is in Crimea.
Russian President Vladimir Putin is due to meet with his top security chiefs and address government and parliament members on the disputed Crimean peninsula on August 14.
The Russian presidential press service said Putin will chair a meeting of Security Council members in the Crimean capital, Sevastopol, and discuss domestic issues, "including those in Crimea," with Russian State Duma lawmakers and federal ministers.
Putin arrived in Crimea for a two-day visit on August 13.
The United States and the European Union have imposed sanctions on Russia over Moscow's unrecognized annexation of Crimea in March as well as the Kremlin's alleged support for pro-Russian separatists in eastern Ukraine.
Prime Minister Dmitry Medvedev and State Duma Speaker Sergei Naryshkin were among the officials accompanying Putin on his Crimean visit.
Ukrainian officials have criticized Putin's visit.
