Police in Yemen have shot and killed an Egyptian man suspected of involvement in this week's attack on tourists in Marib province.

Yemeni officials say the Egyptian died Thursday during an exchange of gunfire as police prepared to storm his apartment in the capital, Sanaa.  Police say they are still tracking down other people suspected of involvement in Monday's bombing.

Three Spanish women and four men were killed when a suicide bomber ran his car into a convoy transporting tourists to an ancient temple linked to the Queen of Sheba.  Two Yemenis also died in the attack and seven people were wounded.

No group has claimed responsibility, but Yemeni authorities say they suspect al-Qaida's involvement.

President Ali Abdullah Saleh has offered a $76,000 reward for information leading to the capture of those behind the attack.

Yemen is the ancestral home of al-Qaida leader Osama bin Laden.  The terrorist group has carried out several attacks in the country, including the 2000 bombing of a U.S. warship in the Gulf of Aden that killed 17 American sailors.

Yemen has pledged its support for U.S. counter-terrorism efforts.
