Police are urging vigilance after four small bombs reportedly exploded in and around Myanmar's largest city in recent days, leaving at least two people dead and several others slightly injured.

Several unexploded devices also have been uncovered.

A police statement posted on Facebook told the public to inform authorities if any suspicious packages are found at bus or train stations, or at the seaport.

Local media reports say the first bomb went off Friday at a guesthouse in Taungoo, a town 200 kilometers (125 miles) from Yangon, killing two people. On Sunday, two other bombs went off, one at a bus stop and another on the bottom of a truck, injuring several.

Police say three people were wounded when a device exploded Monday outside a market in eastern Yangon.
