WASHINGTON: A Senate panel expressed its outrage Thursday over Pakistan's conviction of a doctor who helped the United States track down Osama bin Laden, cutting aid to Islamabad by $33 million, $1 million for every year of the physician's 33-year sentence for high treason.

The punitive move came on top of deep reductions the Appropriations Committee had already made to President Barack Obama's budget request for Pakistan, a reflection of the growing congressional anger over its cooperation in combatting terrorism.

The overall foreign aid budget for next year had slashed more than half of the proposed assistance and threatened further reductions if Islamabad fails to open overland supply routes to US and Nato forces in Afghanistan.

Pushing aside any diplomatic talk, Republicans and Democrats criticized Pakistan one day after the conviction of Shakil Afridi.

The doctor ran a vaccination program for the CIA to collect DNA and verify bin Laden's presence at the compound in Abbottabad where US commandos found and killed the al Qaeda leader in May 2011.

The United States has called for Afridi's release, arguing that he was acting in the interest of the United States and Pakistan.

''We need Pakistan, Pakistan needs us, but we don't need Pakistan double-dealing and not seeing the justice in bringing Osama bin Laden to an end,'' said Senator Lindsey Graham, a Republican, who pushed for the additional cut in aid.

He called Pakistan ''a schizophrenic ally,'' helping the United States at one turn, but then aiding the Haqqani network which has claimed responsibility for several attacks on Americans.The group also has ties to al Qaeda and the Taliban. ''It's Alice in Wonderland at best,'' said Sen. Patrick Leahy, a Democrat. ''If this is cooperation, I'd hate like hell to see opposition.''

One of the most forceful statements came from Sen. Dianne Feinstein, a Democrat who also serves as the chairman of the Intelligence Committee. She pointed out that Pakistan has suffered at the hands of terrorists yet misconstrued what is treason in convicting Afridi. She also insisted that Afridi was not a spy. ''This is a very sad day,'' she said.

The committee approved Graham's amendment to cut the assistance by $33 million on a 30-0 vote. In crafting the overall legislation, the committee reduced Obama's request to aid Pakistan by 58 percent as resentment and doubts linger in Congress a year after bin Laden was killed deep inside Pakistan.

Tensions between Washington and Islamabad have increased as Pakistan closed overland supply routes to Afghanistan after a US attack on the Pakistani side of the border killed 24 Pakistani soldiers in November.

The United States and Pakistan failed to resolve the issue at the recent Nato summit in Chicago.

Members of the Senate committee also complained about mafia-style extortion by Pakistan in seeking truck fees in exchange for opening the supply lines. The cost had been $250 per truck prior to the attack.

Pakistan is now demanding $5,000 per truck. The United States has countered at $500. The bill would provide just under $1 billion in aid to Pakistan, including $184 million for State Department operations and $800 million for foreign assistance.

Counterinsurgency money for Pakistan would be limited to $50 million. The legislation also conditions the counterinsurgency aid on Pakistan reopening the supply routes.

Islamabad will not get any of the funds for counterinsurgency or money in prior legislation unless the secretary of state certifies to the Appropriations committees that ''the government of Pakistan has reopened overland cargo routes available to support United States and Nato troops in Afghanistan, and funds appropriated under this heading can be used efficiently and effectively by the end of the fiscal year,'' the legislation says If the secretary cannot certify to Congress, the money would be transferred to other accounts.

The overall legislation would fund the State Department, foreign operations and other programs at $52.1 billion, which is $2.6 billion less than what Obama requested for the 2013 fiscal year beginning Oct 1 and $1.2 billion below current spending.

The panel also cut money Obama proposed for Iraq by 77 percent, citing the deteriorating security situation there.

The bill would provide $1.1 billion for Iraq, including $582 million in foreign assistance but no money for the police development program. The panel also cut $5 million from the $250 million in economic assistance for Egypt.

Graham said it equaled the amount the US spent to get non-government workers out earlier this year, including Sam LaHood, son of Transportation Secretary Ray LaHood.

Afridi's family appealed against the verdict

The close relatives of the convicted doctor have decided to file an appeal to the FCR commissioner against Afridi's 33-year sentence, DawnNews reported.

Prominent lawyers of Peshawar are being consulted for their legal advice on the matter.

The government has formed 12-member medical team, comprising of high officials of the health department, to medically examine Afridi on daily basis.
