Opponents of Bangladesh's former leader Sheikh Hasina foiled an attempt on Sunday by supporters of her Awami League party to stage a rally in Dhaka, with small scuffles breaking out between the two groups.

Dozens of Hasina's allies were arrested after her regime collapsed -- accused of culpability in a police crackdown that killed more than 700 people during the unrest that deposed her -- while other party loyalists went into hiding.
