On 5 March, a mob set homes, shops and a mosque ablaze in the Digana area of Kandy, in central Sri Lanka.
"Until the national political leadership takes firm and determined action at this time there is an increasing likelihood of Sri Lanka seeing a new cycle of communal violence that will become uncontrollable".
Hakeem said the riots were concentrated in Kandy - home to famous tea plantations and Buddhist relics - but the government wanted to send a strong message given outbreaks of communal violence elsewhere recently.
However, the Sri Lankan Government has chose to impose a state of emergency for 10 days to control law and order, following the violence against the minority community in Kandy district over last two days.
Earlier on Tuesday, the police reimposed curfew in parts of the district after mobs took to the streets on Monday night burning houses and businesses in the latest spate of racial violence to hit the island country.
Sri Lankan President Maithripala Sirisena on March 6 declared a nationwide state of emergency for 10 days in order to curb the communal violence, a day after Buddhists and Muslims clash erupted in Kandy district of the country's Central Province.
Biraj Patnaik, Amnesty's South Asia Director, said, "It is important that the authorities take action against mobs who have incited hatred and carried out acts of violence against religious minorities".More news: Canada unveils new $10 bill featuring female civil-rights pioneer Viola Desmond

The Indian cricket is in Sri Lanka to play triangular series. The attacks followed reports that a Buddhist man had been killed by a group of Muslims. The ethnic clashes between Naypyidaw's state forces and the Rohingya Muslims in Rakhine region has casted a negative impact on Sinhalese-Muslim relations in Sri Lanka as well, they claim.
Tension has been growing between the two communities over the past year.
Najah Mohamed, secretary of NFGG, said the BBS has hatched a conspiracy to fuel anger against the country's 10 percent Muslim population.
"The state of emergency may include curfews in specific locations", the British government said.
"In particular Sri Lankans need to remember the Muslim community has global support in many parts of the world including the Middle East, North Africa, South and Southeast Asia".
Prime Minister Ranil Wickremesinghe said the government condemned the "racist and violent acts". The emergency was finally lifted in 2011.
