Hundreds of Bangladeshi garment workers rallied Sunday demanding fair wages after dismissing the pay offer as too small, as the death toll from the violent protests that erupted last month rose to four. Bangladesh has been rocked by the worst labour unrest in a decade with tens of thousands of workers clashing with police, demanding a near-tripling of the minimum wage to 23,000 taka ($208). Scores of factories have been damaged.

Bangladesh’s 3,500 garment factories account for around 85 percent of its $55 billion in annual exports, supplying many of the world’s top brands including Levi’s, Zara, and H&M.

But conditions are dire for many of the sector’s four million workers, the vast majority of whom are women whose monthly pay, until recently, started at 8,300 taka ($75).

A government-appointed panel raised the sector’s wage by 56.25 percent on Tuesday to 12,500 taka, but garment workers have rejected the hike. Since the pay offer, their protests escalated with at least 70 factories ransacked.

Police said Jalal Uddin, 42, a garment worker who was injured in clashes with officers earlier this month in Gazipur, north of the capital Dhaka, died from his injuries on Saturday.

Uddin’s death takes the number killed in the protests to four, police said.

“He died at the Dhaka Medical College Hospital. He was injured during a protest several days ago,” Bacchu Mia, a police inspector, told AFP.

Uddin’s brother-in-law Rezaul Karim told reporters he had been shot in the stomach by a shotgun and had been brought to Dhaka for treatment.
