A bouquet of flowers with a verse from the Holy Quran in Arabic that reads,”do not fight, or you may fail, and your strength and willpower will weaken,” is seen, as police stand guard, background, during a rally in support of solidarity with Egypt, in Tehran, Iran, Tuesday, April 9, 2013. Last week, a group of angry ultraconservative Salafis protesters threw rocks and tried to storm the residence of Iran’s top diplomat in Cairo, after Iranian tourists arrived in Egypt on the first commercial flights between the two countries in 30 years.
