A group of Burmese Buddhists have blocked humanitarian aid to Rohingya Muslims who have fled from their home in Myanmar to Bangladesh.
Bermese polce clashed with the mob as they were blocking the aid shipment in Rakhine state while nine people have died in a road accident involving a Red Cross truck in Bangladesh.
The incident hampered urgently needed relief efforts for Rohingya who have faced violence in recent months in Buddhist-majority Myanmar.
The mob gathered late on Wednesday at a jetty where a boat carrying relief goods was preparing to travel upriver to Maungdaw. They forced the ICRC (International Committee of the Red Cross) to unload the aid from the boat.
They also prevented the vessel from leaving, according to a newspaper in Myanmar.
Eight people were arrested and several police officers were injured when the mob attacked them.
The ICRC confirmed the incident, saying it would continue to try and deliver relief aids to the area.
"We will carry on; nothing has been put on hold," Graziella Leite Piccoli, ICRC spokeswoman for Asia, told AFP news agency.
Since late last month, when violence against Rohingya erupted in Myanmar, more than 420,000 Rohingya fled into Bangladesh in what the UN calls a campaign of "ethnic cleansing".
