波士頓馬拉松賽發生爆炸, 國內隊員暫無傷情

Police said on Monday that a third explosion hit the Boston JFK Library, but it remains unclear whether it was related to the previous two blasts near the finish line of the Boston marathon.

The blasts killed three and injured 141. One of the dead was an 8-year-old boy, according to a state law enforcement source.

"There was a third explosion at the JFK library," Boston Police Commissioner Ed Davis said at a press conference, adding that he was not yet aware of any injury in the third explosion.

Davis announced a police tipline for information that could lead to the arrest of those who were responsible for the attacks. He also advised people to stay at home or in the hotel.

Meanwhile, US media reports said that the number of those injured in the explosions has soared to over 100.

President Barack Obama has been notified of the incident in Boston, a White House official told White House pool media.

Obama directed his administration to provide whatever assistance necessary in the investigation and response, said the official.

Intelligence officials said two more explosive devices have been found at Boston Marathon before being dismantled, media here reported.

The organizers of the Boston Marathon said on Facebook page that bombs caused the two explosions.

The Boston police bomb squad were sweeping the area for suspicious packages, ABC reported. Law enforcement authorities also told ABC they were testing smoke and materials at the scene for chemical substances.

The two explosions happened at around 3 pm and went off within seconds of each other. The first runners in the marathon crossed the finish line around noon.

The Boston Police Department said two explosions happened on the Boyleston street near the finish line. Local police, fire and bomb squad have arrived at the scene responding to the incident.

引申消息:

當地時間4月15日，美國波士頓馬拉松比賽終點線附近發生至少兩起爆炸，目前造成至少2人死亡，百餘人受傷。

爆炸大約發生於15日下午2點50分（北京時間16日凌晨2點50分）。警方聲明說，爆炸目前造成2人死亡。另據爆炸所在地媒體《波士頓環球報》稱，大約90人在波士頓的醫院接受治療。目前傷者的傷情暫時還不清楚。美聯社等其他媒體目前稱爆炸造成60多人受傷。

美國情報部門對美聯社表示，在爆炸現場又發現至少2個爆炸物，目前已被成功拆除。對於這起爆炸的性質，美國警方正在加緊調查中。

多名目擊者現已證實，現場至少發生兩起爆炸，爆炸發生時人們正在向準備向終點線衝刺的選手歡呼鼓掌。多個視頻顯示，爆炸後的馬拉松比賽場地濃煙滾滾。

在現場的《波士頓環球報》記者西爾維亞（Steve Silva）稱，傷者正在被人用擔架擡離現場，到處是血跡，有人被炸斷了腿，不少人在哭泣。

波士頓警方聯合當地交通部門已將所有通向爆炸現場的道路封鎖。爆炸現場聚集了大量警車和救護車。爆炸現場附近的寫字樓和大型商場都展開緊急疏散。

波士頓警方透露，當天在波士頓的肯尼迪圖書館附近還發生了一起爆炸事件，目前不清楚該爆炸是否與馬拉松比賽有關。

馬薩諸塞州州長帕特里克要求人們不要聚集在公共場所，立即回到家中，等待當局進一步消息。帕特里克稍早前已經和美國總統奧巴馬通話，緊急商討對策。

美國執法部門人員對美聯社表示，當地的手機通信系統已經被緊急關閉，以防止有人通過手機遙控炸彈爆炸。
