Cairo - Egyptian security forces have detained 30 Egyptian truck drivers delivering supplies to the Gaza Strip, a source in the interior ministry told Deutsche Presse-Agentur dpa on Wednesday.

The drivers were held, pending investigation, in Northern Sinai, the source said on condition of anonymity because he was not authorized to speak to the media.

He added that if security forces found nothing after a thorough investigation and search of the trucks, the drivers would be released and allowed to continue their journey.

Egypt has been under increasing pressure from Israel and the United States to do more to stop smuggling into the Gaza Strip, and under pressure from domestic opposition groups to open the border so supplies can reach Palestinians in Gaza. (dpa)
