sentence1: For a second time this week, the southeastern Iranian city of Zahedan was rocked by a bombing. Like the previous bomb blast reported Tuesday, it was relatively small and produced only three injuries and no fatalities. This is in stark contrast to bombs detonated over the weekend in Ahwaz and Tehran, which produced a dozen fatalities and scores of injuries. The Ahwaz bomb went off in a fast-food restaurant at 7:50 PM local time.
sentence2: The city of Zahedan is next to Ahwaz.
