ALEPPO, Syria — Abu Ahmad, who lives in Aleppo's rebel-controlled east, had grown accustomed to sending money at the end of every month to his business partner living in the regime-controlled western part of the city. Abu Ahmad, in his 40s, did not know that the war would one day lead him to open a money transfer office to coordinate cash flow between the two parts of the city.
The border between east and west extends for more than 11 kilometers (6.8 miles). Along it, one sees sandbags, large piles of debris, burnt buses parked on top of each other and hundreds of snipers. It is impossible for anyone to cross the border, lest they be shot dead by snipers.
