DUSHANBE (Reuters) -- A bomb blew up a police car late on July 30 in the Tajik capital, Dushanbe, where the presidents of Afghanistan, Pakistan, and Russia were holding security talks
, an Interior Ministry source said.
Tajikistan, a volatile nation north of Afghanistan, was hosting a summit attended by Afghan President Hamid Karzai, Pakistan's Asif Ali Zardari, and Russia's Dmitry Medvedev.
The source said a bomb planted inside a police car went off, wounding one officer. No one was killed.
"We are trying to figure out whether it was a terrorist act or a personal grudge against this particular policeman," the source said.
Medvedev was still in Tajikistan early on July 31 to attend a ceremony marking the opening of a Moscow-built hydroelectric power station outside Dushanbe.
