Security forces holding press conference right now

Imedia is live-blogging a press conference by security force representatives.

Prosecutor General says there is reasonable suspicion that a terrorist act took place.

Update (11.25 a.m.) - there are suspects. One of the victims saw the person who committed the act.

Update (11.26 a.m.) - Prosecutor General now using the term "terrorist attack" to describe the explosion yesterday.

Update (11.27 a.m.) - Prime Minister was "physically threatened" on the phone, as was the current Government. This happened at about the same time as the explosion.

Update (11.30 a.m.) - One hand grenade was detonated. It was an offensive Soviet-made grenade, which doesn't create a lot of damage, which is probably why there were no casualties. Moldovans still have a lot of weapons left over since the civil war in 1992.

Update (11.32 a.m.) - Is there a connection between Communist head and former President Vladimir Voronin's threat against P.M. Vlad Filat and the detonation? Interion Minister Catan says that Mr. Filat spoke with Mr. Voronin, and both agreed not to make statements that will lead to instability.

Mr. Voronin threatened to "deal with" Mr. Filat during a legislative meeting a few weeks ago.

Update (11.43 a.m.) - Authorities have initiated talks with Transnistrian authorities. One of the hypotheses is that the attack may have been planned from the breakaway region.

Update (11.47 a.m.) - No Moldovan parties would be interested in organizing a terrorist attack, but there are some groups and foreign forces who are against the new Government.

Update (11.50 a.m.) - The man who threatened to detonate a grenade in front of the Prosecuror's Office wants his son released from prison because he says he has been wrongfully accused. There is no connection with what happened in the Square.

Update (11.54 a.m.) - The man apparently bought the grenade, and was even offered a more destructive one.

Update (12.02 p.m.) - The press conference is over.
