Convicted of murdering a 16-year-old girl in 1994, Mexican national Humberto Leal was executed despite White House concerns that US citizens abroad could face harsher punishments as a result.
The gulf in how the US and Pakistan view the murder case against CIA operative Raymond Davis has the potential to make the diplomatic spat get even uglier.
American Raymond Allen Davis, jailed in Pakistan for the fatal shooting of two armed men, was secretly working for the CIA, a disclosure likely to further frustrate US efforts to free the man and strain relations between two countries partnered in a fragile alliance in the war on terror.
A Pakistani court has given the government three weeks to decide whether Raymond Davis, a US official accused of killing two Pakistanis, has diplomatic immunity. The case has brought US-Pakistan relations to a new low.
The US insists the American enjoys diplomatic immunity, but Pakistan won't release him. Hanging in the balance is a summit later this month with leaders from the US, Pakistan, and Afghanistan.
A Pakistan court refused to release Raymond Davis, an employee of the US Embassy in Lahore, saying that diplomatic immunity only goes so far.
The US is claiming diplomatic immunity for Raymond Davis, who shot two Pakistanis last week during an apparent robbery. That could make it harder for the weak civilian government to promote US-backed policies, analysts here warn.
A 6-to-3 majority said the president can't order a state court to abide by an international court ruling.
