A Nepali security personnel examines a blast site in Kathmandu on Sunday.
Security forces in Nepal are on high alert during a general strike called by an outlawed communist group alleged in a series of explosions that killed four people and injured seven more in Kathmandu.
Traffic was thin during rush hour while schools and central markets remained shut on Monday in Kathmandu.
The group had called for a nationwide general strike to force the government in liberating their imprisoned associates.
Police official Shyam Lal Gyawali said specialists were inspecting Sunday’s blasts. The first two blasts happened within minutes distant in two Kathmandu neighborhoods, while the third one was a few hours later.
