Here are the latest developments involving negotiations between Iran and world powers in Vienna over the Islamic Republic's contested nuclear program (all times local):
Pakistan hopes news of a deal over Iran's contested nuclear program will help it complete a gas pipeline linking it to the Islamic Republic.
Pakistan's National Security Adviser Sartaj Aziz said Tuesday he "welcomed" the deal.
Washington for years has opposed Pakistan's bid to import natural gas from Tehran. Pakistan needs the pipeline to supply power to its weak electrical grid.
A Pakistani defense analyst, retired Gen. Talat Masood, told The Associated Press: "Because of this agreement ... I think Washington will stop opposing the Iran-Pakistan gas pipeline project."
Israel's prime minister says a nuclear deal between Iran and world powers is a "bad mistake of historic proportions."
Benjamin Netanyahu said Tuesday that an accord with Iran will allow it "to continue to pursue its aggression and terror in the region."
Netanyahu has been at the forefront of efforts to block an agreement that would lift sanctions on Iran. Iranian officials repeatedly have threatened to destroy Israel in the past. Iran also backs militant groups that attack it.
The talks have been aimed at reaching a final deal to limit Iran's nuclear program in exchange for lifting economic sanctions. Iran long has said its nuclear program is for peaceful purposes. The West fears it could be used to build an atomic bomb.
The head of the United Nations' nuclear watchdog says a "roadmap" has been signed between it and Iran as a final deal has been struck over the Islamic Republic's contested nuclear program.
Yukiya Amano, the head of the International Atomic Energy Agency, made the comments in Vienna on Tuesday, just a short time after diplomats acknowledged a deal had been made between world powers and Iran.
Amano said Iranian Vice President Ali Akbar Salehi signed the roadmap. It calls for his agency, with Iran's cooperation, to make an assessment of issues relating to possible military dimensions of the Islamic Republic's nuclear program by the end of 2015.
Amano says: "This is a significant step forward toward clarifying outstanding issues regarding Iran's nuclear program."
World oil markets are reacting to news that a final deal has been struck between Iran and world powers over the Islamic Republic's contested nuclear program.
In trading Tuesday, benchmark U.S. crude was down $1.20 in trading.
Iran is an OPEC member, but its oil production has been affected for years by sanctions over its nuclear program. Any easing of the sanctions could see Iran sell more oil, which could bring down crude prices.
An Israeli Cabinet minister says a nuclear deal between Iran and world powers gives the Islamic Republic a "license to kill."
Miri Regev, a former military spokeswoman who serves as Israel's culture and sports minister, said Tuesday that the deal was "bad for the free world (and) bad for humanity."
Israel has been at the forefront of efforts to block an accord that would lift sanctions on Iran. Iranian officials repeatedly have threatened to destroy Israel in the past. Iran also has backed militants groups that have attacked Israel.
