Police in Dubai have arrested 10 suspects in a massive knife fight that killed three people, authorities said Wednesday, a relatively rare outburst of violence in the Gulf Arab sheikdom. The police said the melee stemmed from a dispute over money, with 13 men armed with knives and wooden bats fighting over 5,000 dirhams (some $1,360). The brawl drew others in, killing three and seriously wounding more. Police did not identify the suspects beyond saying they were of Asian descent, or specify where the fight took place. Dubai police rarely offer overall crime statistics, but previously have acknowledged similar incidents in low-income expat communities and labor camps, dormitory-style housing for many of the migrant workers from Asia, Africa and the Middle East who drive the machinery of daily life in the emirate.
