Security has been stepped up in townships across Rangoon following the recent spate of bomb attacks across the country.
Police are searching vehicles in the city at night for anything suspicious.
Meanwhile, private security companies have been hired at bridge construction projects in the former Burmese capital.
The security supervisor at Raja Thana private security firm, Yan Naing, said they are coordinating with local authorities to ensure the public’s safety.
“Following the bomb blasts, we were advised by the local police to beef up security,” he said. “Due to the nature of our work, we have been assigned to several large projects.”
He went on to say that the company had been put on alert to ensure a swift response if something untoward happens.
“We have alerted our staff to be on the lookout for bombers trying to enter our sites. Since our personnel are trained, they will immediately notice if something unusual is happening,” he said.
During the past week, a series of explosions have gone off around Burma, killing three people.
In the most recent incidents, on Wednesday night and Thursday morning, three bomb explosions went off in in the northern Shan state town of Namhkam which lies close to the Chinese border.
One person was reported dead and one injured.
Police are still investigating who is behind the attacks but one suspect has already been detained.
President’s office Minister Ye Htut said on Thursday that a press conference would be held on Friday to address the situation.
