(CNN) -- Four suspected militants were killed in a U.S. drone strike in Pakistan's tribal region Tuesday night, a government official and a military official told CNN.
The strike targeted a militant compound in the village of Shawal in North Waziristan, a tribal region bordering Afghanistan, said local government official Siraj Ahmed.
The military official who confirmed the strike asked not to be named because he is not authorized to speak to the media.
The strike comes just one day before Gen. John Allen, the American commander overseeing the war in Afghanistan, meets with Pakistan's top general.
One of the items on the agenda for Allen's meeting Wednesday with Pakistani Army Chief of Staff Gen. Ashfaq Parvez Kayani is reopening the border crossings between Pakistan and Afghanistan, a Pakistani military official told CNN.
Seven months ago, Pakistan stopped allowing U.S. military supplies to cross into Afghanistan from Pakistan through what the United States calls the Ground Lines of Communications, or G-LOCS.
The G-LOCS, which are highway border crossings, were closed after a cross-border NATO shooting left 24 Pakistani troops dead. The U.S. military said it was responding to enemy fire and refused to apologize for the incident.
Senior U.S. officials have expressed regret for the deaths and have issued condolences, but a senior Pakistani diplomat told CNN earlier in June that the lack of an apology is holding up an agreement to open the transit routes.
Until the closing, 30% of U.S. military supplies crossed through the G-LOCS. Since they've been closed, all materiel has had to be flown to bases north of Afghanistan and then moved into the war zone.
U.S. Defense Secretary Leon Panetta testified earlier this month that using the northern routes exclusively costs the United States an extra $100 million a month, compared to when the Pakistan border crossings were open.
Allen and Kayani will also discuss, according to a military press release, recently developed border coordination measures.
