More than 1,000 Tamil protesters occupied the streets outside parliament in central London last Monday.
The demonstration was sparked by news that the Sri Lankan government had bombarded a “safe zone” over the weekend, killing at least 378 Tamil civilians and injuring over 1,200.
The relentless barrage lasted from 5pm on Saturday until 9am on Sunday.
A Channel 4 news team was expelled for reporting on conditions in a government resettlement camp for Tamils.
There has been a constant protest in Parliament Square since 6 April over the Sri Lankan government’s continuing war against the Tamils.
