Harare - Six Zimbabwean activists and a journalist charged with violent attacks following March 29 elections have been released on bail but more than 20 others remain behind bars, their lawyer said on Saturday.

"The seven were granted bail yesterday.... The others are still in remand prison and we are making an effort to secure their release on bail," the lawyer, Alec Muchadehama, told AFP.

They include Luke Tamborinyoka, information director for the opposition Movement for Democratic Change, and Frank Chikowore, a freelance journalist. They were all among some 30 people arrested last month.

The group has been accused of burning a commuter bus, stoning cars and barricading roads after the opposition called for a strike over delays in announcing the results of the elections. - Sapa-AFP
