Formula One drivers and team members as well as key equipment for this weekend's Gulf Air Bahrain Grand Prix have started arriving in the country.

Ferrari star Fernando Alonzo, Sauber ace Sergio Perez and Bruno Senna of Williams were among the first to pass through the airport.

Red Bull Racing test driver and former Toro Rosso frontman Sebastien Buemi and Lotus F1 test driver and former Virgin driver Jerome d'Ambrosio were also spotted.

Trailer trucks with large containers were seen driving to the Bahrain International Circuit under police escort, as teams get ready for the fourth race in the F1 calendar, which starts on Friday.

Gulf Air will be transporting more than 15,000kg of cargo required by teams taking part in this weekend's race.

Gulf Air senior manager Rory Black said carrying F1 material was a huge responsibility and officials had ensured all logistics were in place to transport it safely and securely and in time for the event.

'Having transported and delivered F1 shipments successfully in the past, Gulf Air was the carrier of choice once again this year by the logistics team handling all shipments for the Grand Prix,' he said.

The cargo consists of parts required by individual F1 teams throughout the circuit.

Mystery outsider 'directing intruders'

The two intruders were in constant mobile telephone contact with, and receiving instructions from, an outside source, it was revealed last night (April 17).

A reporter from our sister publication the Gulf Daily News in London said that towards noon, it was clear that orders were being transmitted to them on how to proceed.

When police discovered this, they hacked into the network they were using and immobilised it, said our reporter. They then didn't know what to do, so surrendered.

The Iranian TV channel Al Aalam was the first to broadcast the news of the intruders climbing onto the embassy's rooftop, said our sister paper Akhbar Al Khaleej's correspondent in London.

He affirmed that London-based opposition activist Saeed Al Shehabi was in front of the embassy and was among those who were directing the terrorists through his mobile phone. – TradeArabia News Service
