A decorated military veteran opened fire at the Washington Navy Yard on Monday in a burst of violence that killed 13 people, including the gunman, and set off waves of panic at the military installation just miles from the White House and U.S. Capitol。本周一，一名授勛老兵持槍襲擊了美國(guó)華盛頓海軍基地，包括持槍者在內(nèi)的13人在這起暴力沖突中喪生。海軍基地距美國(guó)首都、白宮所在地僅有幾英里，該事件引起基地人員巨大恐慌。
The FBI identified the suspect as Aaron Alexis, 34, of Fort Worth, Texas, a onetime Navy contractor who attended a Buddhist temple and had two gun-related brushes with the law。美國(guó)聯(lián)邦調(diào)查局證實(shí)，嫌疑人為艾倫-阿萊克西斯，現(xiàn)年34歲，得克薩斯州沃思堡人，曾為美國(guó)海軍基地的非軍人身份合同工，信仰佛教，并合法持有兩把槍支。
He received a general discharge from the Navy Reserve in 2011 after a series of misconduct issues, a Navy official said. 根據(jù)一名海軍官員透露，嫌疑人曾犯有大量不端行為，在2011年被海軍預(yù)備役部隊(duì)解雇。
He was killed in one of several gun battles with police。嫌疑人在與警方的交火中喪生。
The motive - and how he breached
security - remained unknown. About 12 people were injured, Washington Mayor Vincent Gray said, though it was unclear how many of them were shot。目前仍不確定他的作案動(dòng)機(jī)和避開(kāi)安全監(jiān)控的方法。華盛頓市長(zhǎng)文森特·格雷稱(chēng)，大約有12人在本次事件中受傷，但還不清楚其中有多少人受到槍擊。
Hours after the incident, police were searching for a possible second suspect in an incident that raised questions about security at the Washington Navy Yard, about a mile south of the U.S. Capitol and 3 miles from the White House。槍擊案發(fā)生幾小時(shí)后，警方開(kāi)始搜尋本事件可能存在的第二嫌疑人。這一行為令人們對(duì)華盛頓海軍基地的安全性產(chǎn)生質(zhì)疑，該基地位于美國(guó)首都南部1英里處，距白宮只有3英里。
Somehow the gunman managed to enter the Naval Sea Systems Command Headquarters building about 8:20 a.m. (1220 GMT) and started picking off victims from a fourth-floor atrium, witnesses said。目擊者稱(chēng)，早上8點(diǎn)20分，持槍歹徒成功進(jìn)入海軍海上系統(tǒng)指揮總部大樓，在四樓中庭里挑選受害者并一一開(kāi)槍射殺。
It was the worst attack at a U.S. military installation since U.S. Army Major Nidal Hasan opened fire on unarmed soldiers at Fort Hood, Texas, in 2009, killing 13 people and wounding 31 others. 這是2009年得州胡德堡案件之后發(fā)生過(guò)最?lèi)毫拥拿绹?guó)軍事大樓暴力事件。在那起事件中，美國(guó)陸軍少校奈達(dá)·哈桑向沒(méi)有配備武器的士兵開(kāi)火，導(dǎo)致13人死亡31人受傷。
Hasan, who said he acted in retaliation for U.S. wars in Muslim countries, was convicted and sentenced to death by a military jury in August. 哈桑聲稱(chēng)他的目的是報(bào)復(fù)美國(guó)在穆斯林國(guó)家發(fā)起的大量戰(zhàn)爭(zhēng)，他被判有罪，并于八月被軍事法庭執(zhí)以死刑。
