美情報總監下令:禁向「五眼盟友」分享俄烏談判情報
雖然美俄峰會探討和平之路,但俄羅斯在烏克蘭的戰火仍持續。美國哥倫比亞廣播公司(CBS)21日指出,美國國家情報總監加巴德(Tulsi Gabbard)數周前發出指令,禁止美國情報機構向「五眼聯盟」盟友分享有關俄烏和平談判的情報。
「五眼聯盟」是由5個英語國家組成的情報共享聯盟,成員國包括美國、英國、加拿大、澳洲和紐西蘭。
1946年3月,時任英相邱吉爾談到了美英之間的「特殊關係」,以及「席捲整個歐洲大陸的鐵幕」威脅。美英2國率先秘密結成情報聯盟,簽署一項協議,以匯集情報作為對抗蘇聯的壁壘。

The Log Periodic Antenna as known as LPDA is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies.
Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas.
The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements.
With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain.

快訊》南極德瑞克海峽規模7.5強震 海嘯威脅解除
美國海嘯預警系統表示,德瑞克海峽(Drake Passage)地區於台灣時間上午10時16分,發生規模8地震後,未發布海嘯警報。路透報導,美國地質調查所(USGS)表示,今天上午一場規模7.5地震侵襲德雷克海峽。地震規模由原本的規模8下修為7.5。德雷克海峽位於南美洲南端和南極洲之間。美國地質調查所表示,地震深度為11公里。
智利海軍水文與海洋學局一度對智利南極領土發布海嘯預防警報。太平洋海嘯警報中心稍後表示,德瑞克海峽地震的海嘯威脅已經解除。根據美國地質調查所數據,這次地震震央位於阿根廷南端城市烏斯懷亞(Ushuaia)東南方超過700公里處。烏斯懷亞人口約5.7萬人。

鬧區爆炸!雙普峰會前夕 烏克蘭無人機襲俄2大城16傷
俄羅斯與烏克蘭交戰已3年6個月有餘。就在美俄領導人即將於周五(15日)於美國阿拉斯加州舉行峰會之前,靠近烏克蘭的2座俄羅斯城市周四(14日)發生爆炸,當地官員聲稱是烏克蘭的無人機攻擊所致,至少16人喪生。俄羅斯國防部稍早宣稱,防空系統在午夜攔截並摧毀44架烏克蘭無人機。
綜合路透社、《莫斯科時報》、烏克蘭媒體UNN報導,俄羅斯西南部羅斯托夫州代理州長表示,首府頓河畔羅斯托夫(Rostov-on-Don)有一棟公寓大樓遭烏蘭無人機擊中,13人受傷,其中2人重傷。目擊居民稱,轟擊聲震耳欲聾,好幾個街區以外都聽得見,事發前不久,當地才宣布進入飛彈威脅預警狀態,爆炸現場已封鎖。羅斯托夫州位於歐俄西南端,距離與烏克蘭東南部邊境70公里,靠近黑海東北方的亞速海。

美已婚女市長爆偷吃隨扈 挪用210萬公費談戀愛
美國路易斯安那州紐奧良女市長坎特雷爾(LaToya Cantrell)近日遭聯邦檢察官起訴,罪名包括詐欺與貪污,原來她被發現在喪夫前就與前警官兼貼身隨扈瓦皮(Jeffrey Vappie)存在「親密關係」,甚至挪用市府多達7萬美元(約新台幣210萬元)經費談戀愛。而坎特雷爾本是近300年來當地第一任女性市長,如今還成為該市歷史上首位還在任期內遭起訴的市長。
根據外媒《BBC》報導,美國政壇近期被揭露一樁醜聞,現年53歲坎特雷爾是路易斯安那州紐奧良市的市長,檢方指出,自2021年10月起坎特雷爾與貼身隨扈瓦皮,悄悄發展一段「私人且親密的關係」,直到2024年6月瓦皮退休前,兩人多次假藉執勤名義,實際上是跑去約會,其中包含14次國內外旅遊。
檢方同時揭露,坎特雷爾多次私人活動,都以「確保安全」為由讓瓦皮跟隨,將隨扈同行合理化,更能規避審查;至於這些約會的開銷多達7萬美元(約新台幣210萬元),全都從市府的經費中挪用。

《讀賣》:防「台灣有事」共諜趁機滲透 日台罕見簽備忘錄
《讀賣》:防「台灣有事」共諜趁機滲透 日台罕見簽備忘錄
兩岸緊張持續升高,而日本與台灣針對「萬一台灣有事」的情況,罕見簽署了一份合作備忘錄,以共享從台灣入境日本的外國人資訊。這在於透過共享撤離外國人的相關資訊,以防共諜趁亂混入日本,防範境內出現破壞活動。多名日本相關人士透露,日台當局針對台灣緊急狀態簽署諒解備忘錄很罕見。
《讀賣新聞》19日報導,《出入境管制資訊共享合作備忘錄》是由日本對台窗口單位「日本台灣交流協會」去年12月18日與台灣對日窗口單位「台灣日本關係協會」簽署。而交流協會說,備忘錄內容「不公開」。
據相關人士透露,日本依據備忘錄,可從台灣獲得希望入境日本的外國人資訊。這樣一來,一旦有事,日本就能有效進行入境審查,確認是否有可能危害國內治安的人物。事實上,就算平時,台灣機場也會對前往日本的旅客事先加以查驗。
