"The reports of several attacks in Ampara, Kandy and Digana on mosques, businesses and homes during the past week are deeply regrettable," the OIC said in a statement on Wednesday.
The Secretary General of the OIC, Yousef Al-Othaimeen, called upon the government of Sri Lanka to take concrete steps to address the propagation of hatred and violence by extremist groups and to ensure the protection of properties and livelihood of Muslims in Sri Lanka.
At the same time Al-Othaimeen appealed for calm and peaceful relations between communities, and urged the authorities to enforce the rule of law, investigate the incidents and bring the perpetrators to justice, according to the Colombo Page daily.
He said that the Muslim community has a long standing presence in the country and a tradition of living in peace and harmony with their compatriots.
Muslims represent an important and active community that contributes positively to the cultural and economic life of Sri Lanka as a whole, he said.
