A growing number of Americans are donning the keffiyeh, the distinctive patterned scarf that's closely linked with Palestinians, to demand a ceasefire to Israel's attacks on Gaza or to signal their support for Palestinians. The keffiyeh, with its fishing net pattern, is common throughout the Arab world, with roots dating as far back as 3100 BC. It first came to symbolize Palestinian resistance during the 1936 Arab Revolt against British rule and later became the signature head gear of Palestine Liberation Organization leader Yasser Arafat.
