clamp down on

斯里蘭卡外長卡迪爾加馬爾8月12日深夜在其位于科倫坡的住宅內遭暗殺身亡。15日下午斯里蘭卡為卡迪爾加馬爾舉行國葬，斯總理拉賈帕克薩在講話中呼吁國民擱置分歧和國際社會共同努力，鏟除恐怖主義。

外電報道如下：Sri Lankans cremated their assassinated foreign minister Monday as the government urged the international community to clamp down on overseas supporters of Tamil rebels amid fears the killing could scuttle a three-year-old cease-fire.

句中的clamp down on表示"施壓于；壓制；限制；對……進行取締"的意思。例如：The government is clamping down on teenage drinking.（政府正在禁止青少年飲酒。）Following the military coup, there has been a clampdown on press reporting in the capital.（軍事政變以后，對首都的新聞報道進行壓制。）
