The Iranian government is accusing the United States and Britain of being involved in an attack last week that killed 11 members of Iran’s Revolutionary Guard. The Los Angeles Times reports Iranian officials said bullet cartridges bearing a U.S. insignia and English lettering were among the weaponry seized last week from Sunni militants allegedly involved in the attack. The Iranian allegations come a week after the Bush administration accused the Iranian government of supplying sophisticated bombs to anti-U.S. forces in Iraq.
