A state of emergency was extended by Sri Lanka's President Saturday, going back on pledges to relax the tough laws introduced after the Easter Sunday attacks that killed 258 people.
Maithripala Sirisena said in a decree he believed there was a "public emergency" in the country, and was invoking provisions of the public security act extending the state of emergency.
The emergency can be declared for a month at a time, and parliament must ratify it within 10 days.
The tough laws, granting sweeping powers to police and security forces to arrest and detain suspects, were due to expire on Saturday.
Just over 100 people, including 10 women, are in custody in connection with April's Easter Sunday suicide attacks against three churches and three luxury hotels in Colombo.
In late May, Sirisena told diplomats -- from Australia, Canada, Japan, the US and European states -- the security situation was "99 per cent back to normal" and he would allow the emergency laws to lapse by June 22.
He assured diplomats security forces had either detained or killed all those directly involved in the attacks, blamed on a local jihadi group and claimed by the Islamic State group.
There was no immediate word from the government why Sirisena changed his mind, but security remains tight in the capital.
