classrooms and in hallways. we spoke to a student who said he knows the suspect. >> he was a quiet kid. he was nice. i mean i -- i don't know him on a personal level. like we would talk. we were on a hockey team together. but absolutely nothing that would lead me to believe that this could happen. >> we also heard from a doctor at forbes regional hospital. they are treating eight victims three are serious injuries. >> three of those patients had severe injuries and are actually still in the operating room right now. two of those patients are in critical condition but have stabilized. the wounds were all knife wounds. most of them were to the lower abdomen, and they seem to -- to actually almost have a pattern, most were to the right lower abdomen, and that created some

of the criticality of their wounds. >> all of the victims at forbes hospital are male and between ages of 15 and 17. and del, the authorities have not yet determined the suspect's motive. >> and the doctor saying he was an obgyn and delivered many of the kids we was treating. russian troops are massing along the ukrainian border. both the u.s. and the eu voicing fears of an invasion. which russia at this time is denying. many say they want to separate from ukraine just like crimea. kim vannel has our story. >> reporter: the interior ministers ultimatum giving protesters 48 hours to leave state buildings in eastern ukraine either by anything

very keen to avoid any bloodshed. >> we want to go now to phil ittner who is in london, and phil when you were on the ground in kiev you were among the first to report that russia has been behind all of the protests we are seeing, but russia is now blaming the us. so what should we make of this latest war of words? >> that's right. there has been a lot of finger pointing going on as to who might be behind the protests. russia saying there are america contract security force out there some with reslains to the famous black water group. in that has been denied by u.s. officials as the american contracting companies. kiev has been saying they are aware of provocateurs in the

east of the country, and they said we are expecting them to be putting people out there, paying people, agitating to create a me text much as they did in crimea and georgia as well in 2008. so the question is, are these really natural occur -- or cure answers? >> and the russian foreign minister saying they will talk with officials from ukraine. so what should we expect from that? >> well, we do know there are talks being set up somewhere in europe some time next week, supposed to be four party talks between the european union we thus with john kerry being in attendance, the russian foreign minister and the ukrainian foreign minister.

their counterparts. john kerry suggested on tuesday that israel was to blame for the breakdown in negotiations. lisa what exactly did kerry say about the israelis that they are now walking back? >> del, kerry was testifying on capitol hill and asked about the ongoing peace process, and kerry did say that he felt both sides had taken unhelpful actions, but he also said the event that lead to the brink of disaster now began when israel decided not to release the fourth group of palestinian prisoners. >> unfortunately the prisoners weren't released. so day went by, day two, day three went by, and then in the afternoon when they were about to get their 700 settlement

announcements were announced in jerusalem and that was the moment. >> the israelis were not particularly happy to hear secretary kerry say that. they said they are deeply disappointed that kerry would blame israel for the near collapse of these talks. >> and where does this leave now the talks? >> they are clearly on life support. later today the israeli foreign minister will be meeting with secretary kerry here at the state department to discuss where things stand. but the palestinian prime minister has gone to an urgesy meeting with the arab league. when kerry started these talks nine months ago, he gave himself a self imposed deadline, and that was at the end of this month. >> lisa thank you very much. at least 23 people are dead, dozens more wounded in pakistan. a massive explosion ripping

be in texas for fund raisers tonight in houston, and then at an event at the lbj library tomorrow. but this is something that he is duty bound to do, and something he has done in the past. he'll also meet with the families and the survivors as well. >> mike thank you very much. there was more emotional testimony today from oscar pistorius. he is on trial for the shooting death of his girlfriend back on valentine's day of last year. on this his third day of testimony the prosecutor showed this video of pistorius at a shooting range firing at a watermelon, when it explodes, he compares it to the head.
