Since Sudan's president, Omar al-Bashir, came to power in a coup backed by Islamists in 1989, the government in Tehran has seen the Arab-led government in Sudan as a useful ally in north-east Africa. According to Western security reports Iran has used Sudan's vast territory as a corridor for weapons to be smuggled into Egypt and on to Hamas, the Palestinian Islamist group who govern the Gaza Strip.
Israel has previously bombed what it claimed were Iranian convoys in this area three years ago. Katherine Zimmerman, an analyst with Critical Threats, said the Yarmouk attack could be another strike against weapons smuggling networks but "alternatively, it might be an early indicator of increasing likelihood of conflict between Israel and Iran."
In this scenario last week's bombing may have been a pre-emptive strike to deny arms to Iran's allies such as Hamas in the Gaza Strip and Hezbollah in southern Lebanon. Both of these groups would be expected to strike Israeli targets in the event of any future attack on Iran's nuclear programme.
The impact of the increasing confrontation between Iran and Israel over the former's nuclear ambitions could further destabilise the conflict between the Sudans. The former civil war foes returned to brink of an all-out war earlier this year and recently signed a peace deal that some observers regards as a temporary truce. No clear border has been demarcated between the two countries and both governments accuse the others of backing armed rebels inside their respective territories.
