ISLAMABAD The Second EU-Pakistan Summit scheduled to be held in Brussels on April 21 (Wednesday) has been postponed due to halt in European air travel resulting from volcanic eruption, Foreign Ministry said on Monday. According to a press note issued from the Foreign Office, the Second EU-Pakistan Summit will be rescheduled as soon as possible keeping in view the convenience of the both sides. The press note further stated, Pakistan attaches great importance to its partnership with the EU based on commonality of interests. Both sides are, therefore, keen to continue their dialogue and consultations at the highest level and regret the present situation that has resulted in the postponement of the summit. Following halt in European air travel and civil aviation crises resulting from the volcanic eruptions in Iceland and dense ash clouds covering European atmosphere, Prime Minister Yousuf Raza Gilanis visit to Europe has also been called off. Prime Minister Gilani was supposed to leave on Monday for bilateral visit to France followed by the Pakistan-European Union Summit in Brussels. Pakistan International Airlines (PIA) flights to and from European countries have also been affected because of volcanic ash from Iceland. According to media reports, millions of travellers have been hit for the last four days. The disruption is said to be greater than the shutdown that followed the 9/11 attacks. About 20 European countries have closed their airspace and some have extended flight bans beyond Monday.
