Around 400 Tamils are continuing their protest at Londons Parliament Square. Seven people were arrested as the crowd protested against the Sri Lankan governments offensive against Tamil Tiger rebels and alleged human rights abuses. Two men jumped into the Thames as police tried to persuade the crowd to disperse. They were not believed to have been seriously injured. Up to 5,000 people - including women and babies - forced the closure of nearby Westminster Bridge by staging a sit-in on Monday night. The bridge is now open again. The Sri Lankan government has rejected international calls for a ceasefire, claiming it is on the verge of defeating the Tamil Tigers, a rebel group which is fighting for an independent homeland. The protesters say the lives of thousands of civilians are in danger and want the British Government to take action.
