Muslim immigrant men have been accused of six "honor killings" in the United States in the past two years, prompting concerns that the Muslim community and police need to do more to stop such crimes.
"There is broad support and acceptance of this idea in Islam, and we're going to see it more and more in the United States," says Robert Spencer, who has trained FBI and military authorities on Islam and founded Jihad Watch, which monitors radical Islam.
Honor killings are generally defined as murders of women by relatives who claim the victim brought shame to the family. Thousands of such killings have occurred in Muslim countries such as Egypt, Jordan, Pakistan and Palestinian territories, according to the World Health Organization.
Some clerics and even lawmakers in these countries have said families have the right to commit honor killings as a way of maintaining values, according to an analysis by Yotam Feldner in the journal Middle East Quarterly.
