The blood from the slaughtered liverstock, killed by some Muslims to mark Eid al-Adha, or the Feast of Sacrifice, mixed with the flood water - as can be seen in these dramatic pictures.
The city of Bangladeshi capital Dhaka was flooded with bloody water after heavy downpour of rain.
During the celebration, goats, sheep or cows are killed to commemorate Prophet Ibrahim's test of faith.
